(Y, Gd)3Al5O12:Ce nanophosphor was synthesized by co-precipitation method using the mixture solution of ammonium liquor and ammonium hydrogen carbonate as precipitant. The effect of Ce and Gd concentration on the crystallization and luminescence behavior of the phosphor was studied. The results indicate (Y, Gd)3Al5O12:Ce nanophosphor is obtained after the precipitates are sintered at 1,000 °C for 2 h. Following the increase of Ce and Gd concentration, the emission shows red shift.
