Photoluminescence Studies on LiNa5(PO4)2:Eu3+ Phosphor

Abstract

In this paper, LiNa5(PO4)2:Eu3+, a new class of phosphor, was prepared with different concentrations of Eu3+ by solution combustion synthesis. This series of prepared materials were investigated by using various experimental techniques. X-ray diffraction confirmed a consistent orthorhombic phase and agreed with the standard JCPDF data. This phosphor exhibits intense d red emission peaks at ~612 nm corresponding to 5D0–7F2 transition upon 392 nm excitation. The color of the emitting light is red, and the calculated chromaticity coordinates are well placed in the red region. The results indicate that the present phosphors could be the potential candidates for the source of red color both in lasers and in light-emitting diodes.
