Abstract:The red phosphors which can be effectively excited by the blue chip and have broad emission bands are reviewed and discussed in this paper. It is obtained that the phosphors mainly include alkaline earth sulfides, novel nitrides and silicates, and have the same characteristics of broad emission band when excited by the 460 nm blue LED chips. Moreover, the correlation between the crystal structure and the luminescent properties is emphatically analyzed, and some view points on the investigation and application of the red phosphors for high color index and adjustable color temperature white LEDs are proposed.
