Rare earth phosphors: fundamentals and applications,

24-07-1998· Here, the green emitting phosphor applied also is a rare earth phosphor; in most cases Y 2 SiO 5:Tb is used. Contrary to the ZnS phosphors, the rare earth activator ion concentrations can be chosen relatively high (in the order of 5%, whereas the activator concentrations in ZnS phosphors are in the order of 100–1000 ppm).Rare earth phosphors: fundamentals and applications,,The application potential of rare earth phosphors with regard to new developments such as phosphors for LEDs and luminescent materials with quantum yield larger than unity is also discussed.
