Outdoor glow in the dark paint – The key to shining in the darkness of painting is a family of substances know as phosphors or phosphorescent materials. These substances have special qualities that allow them to produce their own light under certain circumstances. Many of these substances are heavy metals or comptoxic substances. So it cannot be use throughout the paint. But the particles of phosphorescent materials are mix with paints design to keep the particles in a substrate. Zinc sulfide, strontium aluminates, and alkaline earth silicate are some of the substances Zinc sulfide is approve for use in body painting.
When the phosphorescent materials come into contact with the light energy. It absorbs some of the energy and maintains it in what is know as a “metastable” state. This means that the light is not reflect immediately. As is the case with most of the substances or their total absorption. But remain in the atoms of the substance, which with more energy. Over time, atoms release this accumulated energy in the form of photons. A delay release that causes the substance to shine after the light is gone.

Depending on the outdoor glow in the dark paint, some types of light are activating, and some types are emitting. Activation wavelengths are the ones that the paint is absorb. And hold while the emission wavelengths are the type of light which the paint will produce. Usually a different color to that of absorbed light. Red, orange and green light emitter is the most common. While some versions of aluminates also emit blue. Chemiluminescence is a term use for short-term products that glow in the dark using solutions that interact with each other to form chemical light. Instead of absorbing light from other sources, these solutions exchange energy and produce light waves from other sources .
While these substances are not highly toxic, they are rarely use as they outdoor glow in the dark paint. Because they only last for several hours before they disappear. Sometimes chemiluminescence painting is use in entertainment events. Paint that shines in the dark comes in two different varieties, a species mark “diurnal” and a species without the day tag. Daytime paints are lighter and show the colors of the paint underneath the coating for the daytime displays. While it shines intensely with their own colors in the dark. Paints without daytime features are opaque. And their colors are only seen in low light.
