Abstract

The orthophosphate phosphors, Ba3La(PO4)3 activated with Dy3+ and Gd3+Dy3+ 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 Gd3+ greatly enhances the Dy3+ luminescence under 172nm VUV excitation. The measurements on excitation spectra, emission spectra, and luminescence decay curves revealed that the energy transfer between Gd3+ and Dy3+ becomes more and more efficient with the increasing Gd3+ contents.
