FAQ

What is Strontium Aluminate?
Strontium Aluminate is a phosphor that will glow after exposure to light when combined with certain types of elements. Europium is the element most commonly used to produce this glow.

How do photoluminescent products charge?
Our glow in the dark Strontium Aluminate materials charge when exposed to light, such as sunlight, fluorescent lights, or incandescent lights. UV light excites the electrons in Europium, thereby “charging” the material.

What makes photoluminescent products glow in the dark?
When the Europium electrons return to their normal ground state, they release the photons that make our materials glow.

How long do photoluminescent products glow?
AfterGlow’s Photoluminescent Safety Solutions™ glow between 6 and 10 hours, depending on the product.

Can I use photoluminescent products outside?
