Title: Enhancement of photoluminescence properties of green to yellow emitting Y3Al5O12: Ce3+ phosphor by AlN addition for white LED applications
Abstract: AlN-substituted in Y3Al5O12: Ce3+ phosphor was synthesized to improve the phosphor efficiency of phosphor-converted white light emitting diodes. The photoluminescence properties of AlN-substitued for Al2O3 in Y3Al5O12: 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.
