It is also used as a green phosphor in projection CRTs, though its drawback is marked lowering of efficiency at higher temperatures. Variants include, for example, using praseodymium instead of terbium ( CAS registry number 68609-42-7 , EINECS number 271-826-9), or using a mixture of dysprosium and terbium for doping (CAS number 68609-40-5 ...

When activated with a suitable dopant (Europium and Dysprosium), it acts as a photoluminescent phosphor with long persistence of phosphorescence. This technology offers up to ten times higher brightness than previous zinc sulfide–based materials. These types of phosphorescent pigments, often called lume, operate like a rechargeable light ...

In turn, other materials (such as nickel) can be used to quench the afterglow and shorten the decay part of the phosphor emission characteristics. The electronic configuration of the activator depends on its oxidation state and is crucial for the light emission. Oxidation of the activator is one of the common mechanisms of phosphor degradation.
