摘要：

This research note reports the fluorescence properties of Eu3+-doped in three sets of (Y-Zn, La-Zn and Gd-Zn) oxyfluoride powder phosphors. On excitation with a UV-source, these phosphors have displayed orangish-red color and for which the chromaticity coordinates ((X) over bar,(Y) over bar) have been computed. The relative fluorescence intensity ratios (R) for the different measured emission transitions have been evaluated in order to examine the effect of substitution of zinc ions in the host matrix on the fluorescence behavior. Scanning electron microscopy studies have also been performed to investigate the average grain size of the synthesized phosphor material.
