Valgusvärvide

Valgusvärvide is a term used to describe paints or coatings that exhibit phosphorescence, meaning they absorb light energy and then emit it slowly over time, creating a glowing effect in the dark. These paints are typically non-toxic and are often based on phosphorescent pigments. The glow is a result of the pigment's ability to store energy from light sources such as sunlight or artificial light and then release it as visible light when the ambient light is low.

The duration and intensity of the glow depend on several factors, including the type and concentration of the phosphorescent pigment used, the thickness of the applied paint layer, and the amount of light absorbed. Common applications for valgusvärvide include safety signage, decorative items, children's toys, and artistic creations. They are also used in the textile industry for clothing and accessories that need to be visible in low-light conditions.

The technology behind valgusvärvide has evolved significantly, with modern formulations offering brighter and longer-lasting luminescence compared to older versions. The pigments are often based on strontium aluminate, which provides a strong and durable glow. When the paint is exposed to light, the electrons within the pigment particles become excited and move to a higher energy level. As they return to their normal state, they release this stored energy as photons, creating the visible glow.
