纳米晶Y_2O_3∶Eu^(3+)氧化物颗粒均匀性的研究

Study on Particle-Size Distribution of Y_2O_3∶Eu^(3+) Oxide

利用草酸沉淀工艺制备了纳米晶 Y2 O3∶ Eu3+ 氧化物 ,并研究了溶液浓度、反应温度、沉淀方式等因素对制备纳米晶 Y2 O3∶ Eu3+ 氧化物粒度的影响 。

The nanocrystalline of Y 2O 3∶Eu 3+ oxides had been obtained with technology of oxalic acid precipitation.The effect factor on the preparation such as concentration of aqueous reaction temperature and precipitation method and so on had been studied.Finally,the agglomerate size and particle sixe distribution of Y 2O 3∶Eu 3+ oxide powders had been controlled with the steric stabilization effect of the surfactants.
