Preparation of YAG:Ce yellow phosphor by step-by-sty precipitation method

摘要：

The high-brightness LED with (Y0.98-xGdxCe0.02)3Al5O12 yellow phosphor is be obtained by step-by-sty precipitation method, and used the 0.1mol/L ammonium bicarbonate and aqueous ammonia to be precipitant. The effect of Gd3+concentration on (Y0.98-xGdxCe0.02)3Al5O12 is investigated at room temperature(RT). The results show that, the relative intensity increased with increasing content of Ce,and achieve the maximum value at x=0.06, then followed by weakening trend, the intensity of phosphors that adding flux increased by 50％, the peak wavelength changed about 5nm to 10nm by addition of Gd3+from 0 to 0.3mol and optimal luminescent intensity happens at 0.1mol Gd3+doping. The experiment results proved that the phosphors remain structure of Y3A15O12 phase when the Gd3+doping.
