The synthesis and luminescence properties of Eu3+-doped ordered olivine-type NaLnGeO(4) (Ln = rare earth) phosphors are reported. Under vacuum-UV (VUV) excitation, this phosphor showed intense red emission due to the D-5(0)-F-7(2) 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)(2)O-3.
