Abstract
The research progress of light converting inorganic phosphors for white light-emitting diodes (WLEDs) in recent years is reviewed. The yellow, green and red phosphors excited by blue LED chip and the yellow, green, red, and single matrix white phosphors excited by near ultraviolet LED chip are overviewed respectively. The phosphors with preferable properties are mainly recommended. The photoluminescence spectra and their tunable mechanism of relevant aluminate, silicate, nitride ( oxynitride ) and molybdate are described briefly. The urgent problems to resolve in this field are pointed out and the development tendency is prospected.
