Abstract

Abstract The synthesis and luminescence properties of Eu3+-doped ordered olivine-type NaLnGeO4 (Ln = rare earth) phosphors are reported. Under vacuum-UV (VUV) excitation, this phosphor showed intense red emission due to the 5D0-7F2 transition. The Na(Y0.3Gd0.65Eu0.05)GeO4 phosphor with optimum composition and synthetic condition under 147 nm excitation were higher than those of (Y0.95Eu0.05)2O3.
