WebMaterials. 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. However, the development of strontium aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to ... WebContact us. Lumilux SN-series are phosphorescent pigments that store energy when exposed to the sun or an artificial light source, and emit light long after the source has been removed. They are strontium aluminate-based, which feature significantly higher initial brightness and longer afterglow periods than zinc-sulfide based products.
