The aim is to produce zinc sulfide crystals doped with copper impurities. This creates a phosphor with a familiar green glow. [Hydrogen Time] starts by noting that it’s important to make sure ...

Laser lighting is considered as a next-generation high-brightness semiconductor light source, and the laser-excited phosphor (LEP) technology is the common method to produce laser-driven white ...

Used for large displays such as wall-sized advertisements on the sides of buildings, Laser Phosphor Display (LPD) is reminiscent of the CRT, but uses lasers instead of an electron gun to activate ...
