摘要：

A monodispersed Al2O3@YAG: Ce core-shell phosphor has been synthesized by coating Y2O3: Ce film on Al2O3 particle. The phosphor has particles size of 60-120 nm and shows high dispersity due to the high dispersed Al2O3 particles prepared by nonaqueous precipitation method. The core-shell structured phosphor consists of a corundum core and a YAG shell. The Al2O3@YAG: Ce core-shell yellow phosphor presents high yellow emission. The light-emitting diode (WLED) based on this yellow phosphor and InGaN blue chip displays high white purity. This Al2O3@YAG: Ce core-shell phosphor can be viewed as a promising candidate yellow phosphor for white LEDs.
