Preparation and Luminescence Characteristics of Li₂Y_4-XEu_x(WO₄)₇ Red–Emitting Phosphor

Article Preview

Abstract:

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 5D0→7F2 transition of Eu3+ at 615nm, and they can be used for white LED.
