摘 要：<正>In an effort to develop new green-emitting PDP phosphors with high efficiency, investigated were the synthesis, VUV photoluminescence （PL） spectra, optical properties, and chromaticity of Ca（La1-x-yTbxGdy. ）4Si3O13 phosphors by using synchrotron radiation. Upon analysis of the VUV spectroscopic and chromaticity investigations on the new greenemitting VUV phosphors, were an optimized composition achieved. The PLE spectral studies show that Ca （ La1-x-y TbxGdy）4Si3O13 exhibit significant absorption in the VUV range. The VUV PL intensity was found to enhance with Gd3+-doping. Furthermore, the 1931 CIE chromaticity coordinates of Ca（La,Gd）4Si3O13:Tb were found to be （0.286, 0.548）, as compared to （0.230, 0.712） for Zn2SiP4:Mn2+ as a reference. The potential application of Ca（La,Gd）4Si3O13:Tb as a new green-emitting PDP phosphor are being currently improving and evaluating.
