What are Glow in the Dark Pigments?

Glow in the dark Pigments, also known as photoluminescent glow powders, are a blend of phosphorescent materials that can absorb and store light energy. When exposed to a light source, such as sun light or artificial light, these powders capture the luminous energy and then release it in the form of a glow. Strontium aluminate is a commonly used phosphor that makes these glow in the dark pigment powder truly shine.

What are Photoluminescent Powders made of?

Glow in the dark pigment powder can be inorganic and organic and is non radioactive. Each variety possesses its unique qualities, opening up a world of possibilities for artists and creators who want to use the magic of phosphorescent glowing creations. Let's look into their distinct characteristics.

Inorganic glow pigment - Minerals and Metals

Crafted from minerals and metals like zinc sulfide, strontium aluminate, or europium-doped yttrium oxide, inorganic pigments are considered as the classical fluorescent pigment. They are known for their durability, stability, and exceptional brightness. These inorganic fluorescent pigment powders promise a longer-lasting phosphorescent glow but demand a bit more energy to charge and boast a shorter fluorescent time. Yet, these phosphorescent strontium aluminate glow powders are perfect for creations where a vivid and enduring glow is desired, making them perfect for projects where longevity is a top priority.

Organic non-toxic Fluorescent Pigments - Versatile Eco-Friendly Glow

As mentioned before, there are also organic glow in the dark pigments. These are created from carbon-based molecules such as dyes, polymers, or bioluminescent organisms. These glowing powders not only add phosphorescent radiance to your creations but also have the advantage of being non-toxic, making them an eco-friendly fluorescent and safe choice for your projects. Organic glow in the dark pigment powder are known for their flexibility, versatility, and eco-friendliness. It's essential to note thatthe phosphorescent organic pigments tend to have a shorter lifespan and lower brightness than inorganic glow pigment. Also, their sensitivity to heat and UV light may require extra care in their use, making them ideal for projects where a brilliant but temporary phosphorescent glow is preferred.

Achieving Long-Lasting Fluorescent Radiance 

The magic of these long-lasting glow in the dark powders lies not only in their ability to glow but also in their longevity. These glow pigments can last up to 7 hours, depending on how long they have been charged up with lights. You can also charge the glow in the dark pigments with your phone flashlight for a couple of minutes, which will result in a short but noticeable fluorescent glow. If you charge the glow pigment during the daytime using natural sunlight or lamps, the best effects of their glow will typically be observed within the first 3 hours of their illumination. During this initial period, the phosphorescent pigments will emit their brightest and most vibrant glow. The phosphorescent intensity also depends on the placement of your creation, so it would be ideal to place it where it can have direct lights to charge for a couple hours. However, keep in mind that for it to fluorescent intensely, darker surroundings are needed. This means that if there will be lightssources nearby, the phosphorescent glowing will be less intense or even not visible at all, depending on the brightness of the area.

In the following, we will explain the charging and glow times of phosphorescent pigments depending on the source of light: For glow in the dark products, a charge time of 3-4 minutes of exposure to (UV) ultra-violet black light will activate their luminous properties. When placed under direct sunlight for approximately 7-8 minutes, glow in the dark products absorb enough light energy to produce a phosphorescent glow. To charge your phosphorescent products using fluorescent light (strip lighting or energy-saving bulbs), you will need to expose them to this light source for approximately 21-23 minutes. If you prefer using traditional incandescent light (standard filament bulbs) to charge your glow in the dark products, you'll need to expose them to this light source for about 24-26 minutes. 

The longevity of glow in the dark paint also depends on several factors. If the painting surface is in good condition and the fluorescent pigment paint was applied correctly, the phosphorescent will last lifetime. Proper application and maintenance can significantly extend the lifespan of the glow in the dark paint, allowing you to enjoy its phosphorescent radiance for many years to come. Other factors, such as the quality of the glow pigment powder and paint, the exposure to sunlight, and the local weather conditions, are also influential.

Phosphorescent Colors Glow brighter 

Color variations of glow in the dark pigments are fascinating to explore. Phosphors typically produce shades of blue, green, and yellow. These phosphorescent colors are commonly seen in traditional glow in the dark products. However, glow pigment powders are capable of producing a wider range of colors, including red, orange, pink, and purple. Some glow in the dark pigment colors may appear less vibrant or get lost when mixed into certain paints or mediums. This is because the base color of the paint can influence the final appearance of the Phosphorescent pigment powder. For example, if you mix a blue glow in the dark pigment with a yellow paint, the resulting color may appear green under the UV black light due to the combination of the blue glow and yellow base color. Similarly, mixing a fluorescent green glow in the dark pigment powder with a blue paint may result in a turquoise phosphorescent glow. To achieve the desired fluorescent pigment powder color, it's essential to consider the color of the base paint or medium you're using and how it will interact with the fluorescent pigment powder. Some experimentation with the UV black light may be needed to find the best phosphorescent pigment powder combination that allows the glow in the dark effect to shine through while maintaining the integrity of the fluorescent pigment color.

Neon Glow in the Dark Pigment and Paint

Neon glow in the dark paint, also known as fluorescent glow in the dark paint, combines the qualities of both neon colors and glow in the dark pigments. During daylight or under regular lighting, neon glow paint exhibits vibrant, eye-catching neon colors that are similar to fluorescent colors. When the lights are turned off, the paint emits a vibrant glow that can be in the same color as the neon hue or a complementary shade. In general, neon glow in the dark paint provides a more intense and attention-grabbing glow compared to regular glow in the dark paint. The combination of neon colors and glow effect creates a striking visual impact.

What is the difference to Non-Neon Glow in the Dark Paint?

The main difference between regular glow in the dark paint and neon glow in the dark paint lies in their appearance and the type of illumination they provide. Regular glow in the dark paint contains phosphorescent pigments that absorb and store light energy when exposed to light sources, such as sunlight or artificial light. When the lights are turned off, the stored energy is gradually released in the form of a soft, glowing light. This effect is often green or blue in color, resembling the natural glow of phosphorescent materials. The glow from regular glow in the dark paint is usually subtle and emits a calming, ambient light. It is often used for creating a soft luminous effect on various surfaces. Regular glow in the dark paint produces a subtle, soft glow after being charged by light sources, while neon glow in the dark paint offers bright neon colors during daylight and transforms into a vibrant, glowing hue in the dark. The choice between the two depends on the desired visual effect you want to achieve for your projects or decorations. In summary, neon glow in the dark paint offers the dual advantage of bright colors during the day and an intense, glowing effect in the dark. It is often used for creating visually striking decorations, artwork, and designs that command attention both during daylight and nighttime hours. Regular glow in the dark paint, on the other hand, provides a more subdued and natural glow, suitable for adding gentle illumination to various surfaces.

The Diverse Applications of Glowing Pigments

The diverse applications for glow in the dark pigments know little to no limits. In the following sections, we will explore the wide range of usage possibilities, from epoxy resin to plastic and everything in between.

Mixing and Applying glow pigment

In the following, we've noted some essential tips and tricks to guide you through the process of mixing, applying, and creating captivating phosphorescent glowing coatings. As mentioned before, the versatile fluorescent pigments can be mixed with non-water-based mediums, opening up a world of possibilities. Clear mediums like resins, solvents, sealers, varnish, lacquer, and inks are among the mediums that blend seamlessly with the phosphorescent glowing pigment. Remember, it's best to add your chosen medium to the glow in the dark pigment, not the other way around, to ensure a smooth phosphorescent blend.

When mixing, opt for a viscous (thick) medium to prevent the phosphorescent particles from settling too quickly. Transparent mediums work wonders, enhancing the glow in the dark pigment brightness of the shining. Take caution to choose a medium with low acidity, as high acidity can damage the radiance. Always check with the manufacturer of your chosen medium to ensure compatibility.

How Much Fluorescent Glowing Powder to Use

For mixing your phosphorescent pigments and powders, opt for plastic spatulas and mixing bowls. Steer clear of metal equipment to avoid any adverse reactions with the luminescent glow pigments. Mixing ratios can vary depending on your application, and it's crucial to listen to the recommendations of your medium's manufacturer. For instance, if you're blending phosphorescent glow powder with clear resin, 6% pigment load is a standard starting point, but to add a 10% pigment to 90% medium ratio usually suffices.

Applying Photoluminescent Pigments

Applying glow in the dark powder is an art in itself. If you've created phosphorescent paint or varnish, use a brush or paint roller to add it to a dry surface. Remember, a thin layer won't perform as well as a thicker one; a heavier coating increases the glow time and its fluorescent brightness. For optimal results, 2-3 coats may be necessary. After the coating is dry, protect it with a clear top coat for extra durability and a lasting phosphorescent glow. For the most captivating effect, apply the finished glow coating to a light or white background or basecoat. Dark backgrounds may deplete the glow's brilliance.
