摘要
本文用络合－沉淀法制备了Ｙ２Ｏ３：Ｅｕ超微粉末，平均粒径０．０４μｍ～０．１μｍ，ＸＲＤ分析为立方晶系。试验结果表明，Ｙ２Ｏ３：Ｅｕ的平均粒径和相对亮度随焙烧温度的增加而明显增加；超微状态下的Ｙ２Ｏ３：Ｅｕ相对亮度低；Ｙ２Ｏ３：Ｅｕ的平均粒径对相对亮度有很大影响。
Y2O3:Eu uitrafine powders were prepared by complex-precipitation method.The mean particle size of Y2O3:Eu is 0.04-0.1um. XRD resuit shows that Y2O3:Eu ultrafine powders are cubic structure. It was found that the mean particle size and relative brightness of Y2O3:Eu increases obviously with the increase of calcination temperature. The relative brightness of Y2O3:Eu ultrafine powders is low. The mean partical size of Y2O3:Eu has great effect on the relative brightness.
