Abstract

Fine size (Y,Gd)BO₃:Eu phosphor powders with high photoluminescence intensity under vacuum ultraviolet were prepared by spray pyrolysis. The precursor powders with hollow shape and large size were prepared by spray pyrolysis from the spray solution with citric acid. The precursor powders turned to the (Y,Gd)BO₃:Eu phosphor powders after post-treatment at temperatures between 900 and 1100 °C. The mean sizes of the phosphor powders post-treated at a temperature of 950 °C were 0.37 μm. The photoluminescence intensity of the fine size (Y,Gd)BO₃:Eu phosphor powders was 95% of that of the commercial (Y,Gd)BO₃:Eu phosphor powders with micron sizes.
