White light-emitting diodes(LEDs)have recently been receiving attention as light sources because of their energy efficiency,long lifetime,compactness and environmental friendliness.The white light can be generated by using an LED chip-phosphor system,being termed phosphor converted LED(i.e.pc-LED),in which the phosphor strongly absorbs blue light(~460 nm)from LED chips and efficiently re-emits in the red,green,or yellow parts of the visible spectrum.This revolution has led to the identification and development of numerous potential phosphor materials for further improvement of the light quality and extending LED applications.
