Strontium aluminate is an aluminate compound with the chemical formula SrAl2O4. It is a pale yellow, monoclinic crystalline powder that is odourless and non-flammable. When activated with a suitable d
Europium doped strontium silicate-aluminate oxide powder under visible light, long-wave UV light, and in total darkness.
Green (emission at 515 nm) C3 Super-LumiNova applied on a diver's watch to make it readable in low light conditions.
Blue-green (emission at 485 nm) BGW9 Super-LumiNova applied on a similar diver's watch face.
Reusable and non-toxic glow stick made from strontium aluminate particles mixed with a settable material. The different colours are made from slightly different strontium aluminate formulas.
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light of a shorter threshold wavelength, a phosphorescent substance will glow, absorbing the light and reemittin

An extremely intense pulse of short-wave UV light in a flashtube produced this blue persistent-phosphorescence in the amorphous, fused silica envelope, lasting as long as 20 minutes after the 3.5 microsecond flash.
An electron microscope reveals vacancy defects in a crystalline lattice of molybdenum disulfide. The missing sulfur atoms leave dangling bonds between the molybdenum atoms, creating traps in the empty spaces.
