摘要
A series of novel red light-emitting phosphors Li2Y4-xEux(WO4)(7) were synthesized by solid-state reaction. The phosphors were characterized by XRD and luminescence spectra. The results show that the phosphors can be excited by near-UV light of 395nm effectively. The relative intensity of the sample reaches a maximum when x is 2.8. The main emission line is D-5(0)-> F-7(2) transition of Eu3+ at 615nm, and they can be used for white LED.
