Phosphors for General Lighting
The aluminate phosphor system, including YAG (yellow), GaYAG (greenyellow) and LuAG (green), can achieve large tunable emissions peaking from 499 to 575 nm. Owing to the high quantum yield and excellent chemical stability, aluminate phosphors become one of the most important phosphor systems in general lighting field.
