Abstract

AlN-substituted in Y₃Al₅O₁₂: Ce ³⁺ phosphor was synthesized to improve the phosphor efficiency of phosphor-converted white light emitting diodes. The photoluminescence properties of AlN-substitued for Al₂O₃ in Y₃Al ₅O₁₂: Ce³⁺ phosphor showed excellent green to yellow emission intensity under 460 nm. The highest emission intensity was observed at an AlN concentration of 0.3 mol and a Ce³⁺ concentration in the optimized flux of 0.20 mol. The green to yellow emitting AlN-substituted in Y₃Al₅O₁₂: Ce³⁺ phosphor can be applied to white LEDs.
