Is a class of newly developed phosphorescent (glow-in-the-dark) pigments which are based on Strontium Oxide Aluminate chemistry. They are drastically different from conventional phosphorescent pigments which are either based on Zinc Sulfide or on radioisotopes for their self-luminous properties. LumiNova® Pigments are in the TSCA and EINECS inventory and Nemoto & Co., Ltd. was granted the U.S. Patent in 1995 and since then in many other countries
The classic “glow in the dark” or phosphorescent pigments consist of very fine crystals of zinc sulfide doped with copper (ZnS:Cu). The glow is due to the unique properties of crystalline zinc sulfide. Copper is added to the zinc sulfide as an activator. This allows the crystals to absorb light and slowly emit it over time. This slow emission is called phosphorescence.
