摘 要：A novel technique for YAG:Ln（Ln=Eu,Ce） phosphor powder synthesis with a nanocrystalline structure was developed.Nanocrystalline YAG:Ln powder was prepared by an ultrasonic atomization and co-precipitation method using a mixture solution of ammonium hydroxide（NH3·H2O） and ammonium hydrogen carbonate（NH4HCO3） as precipitant.The as-prepared nano-powders were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,and fluorescence spectrometer.The obtained phosphor powders were homogenous and in size of 50-70 nm.The results demonstrated that by using ultrasonic atomization and co-precipitation process,we could synthesize a good quality YAG:Ln（Ln=Eu,Ce） phosphor powder that had many potential applications.
