Abstract

The orthophosphate phosphors, Ba 3 La ( P O 4 ) 3 activated with Dy 3 + and Gd 3 + Dy 3 + ions, were prepared by a solid reaction technique at high temperature. Their spectroscopic properties were investigated in the vacuum ultraviolet (VUV)–visible range. We found that the introducing of Gd 3 + greatly enhances the Dy 3 + luminescence under 172 nm VUV excitation. The measurements on excitation spectra, emission spectra, and luminescence decay curves revealed that the energy transfer between Gd 3 + and Dy 3 + becomes more and more efficient with the increasing Gd 3 + contents.
