Common pigments used in phosphorescent materials include zinc sulfide and strontium aluminate. Use of zinc sulfide for safety related products dates back to the 1930s. The development of strontium aluminate pigments in 1993 was spurred on by the need to find a substitute for glow-in-the-dark materials with high luminance and long phosphorescence, especially those that used promethium.

As phosphorescence is often quite weak, the reaction is best observed in a darkened room. The observed duration can persist from less than a second to a few tens of seconds. Blue and colorless HPHT-grown synthetics often show light blue phosphorescence, with the luminescence spectral band centered at 500 nm. homedics jet spa elite with heat manuel
