|Assorted glow-in-the-dark paints.|
This lovely array of glow-in-the-dark (phosphorescent) powders illustrates the range of colors and the brightness of modern luminous paints. Green and aqua are europium doped strontium aluminate, the brightest of all the modern phosphorescent powders. Blue is a alkali earth silicate, while red and orange are older, noticeably less bright zinc sulfides. (The difference in brightness is so great it was difficult to get a photograph that showed the glowing of the zinc sulfide without overexposing the other colors!) The powder packets are meant to be mixed with paint, nail polish, or whatever, rendering them luminous. The bottle in the back is ready-made paint, while the small tub is a heat-and-dip powder.

(The "purity" listed below doesn't mean a whole lot since this is a mixture of several different compounds: I'm just indicating that this sample is not a simple element but rather a mixed compound.)
