Abstract

The effect of processing conditions on the photoluminescence properties of the Ca(Y_0.94Eu_0.06)BO₄ phosphors that were synthesized by ultra-sonic spray pyrolysis was investigated. The morphology and size of the Ca(Y_0.94Eu_0.06)BO₄ phosphors were controlled by changing processing conditions, including precursor concentration, organic additives content, and air flow rate, and substantially affected their luminescent properties. Lower precursor concentration yielded higher emission intensity. High emission intensity was obtained for an air flow rate of 5-20 l/min. The magnitude of the emission intensity on organic additive concentration followed the order of 0.5 M>0.3 M>0.7 M.
