摘要: 利用Nano317型激光粒度分析仪对纳米Gd2O3:Er3+的粒径测定样品处理方法进行研究，分别考察了分散介质、纳米Gd2O3:Er3+溶液的浓度、分散剂种类及用量、超声震荡和静置时间等处理条件对粒径测定的影响。结果表明：以蒸馏水为分散介质，纳米Gd2O3:Er3+的浓度为0.1 g/l，1 g/l六偏磷酸钠为分散剂，超声时间大于30 min时，激光粒度分析仪测定值达到稳定，测得粒径大小与扫描电镜结果一致。
Abstract: Using the Nano 317 laser particle size analyzer to study the particle size of nanometer Gd2O3:Er3+, respectively investigates the dispersion medium, Nano Gd2O3:Er3+ solution concentration, kind and amount of dispersants, ultrasonic oscillation and static time and so on processing conditions on measurement of particle size. The results showed that the distilled water as dispersion medium, nano Gd2O3:Er3+ concentration is 0.1 g/l, 1 g/l sodium hexametaphosphate as dispersant, ultrasonic time greater than 30 min, laser particle size analyzer to determine value achieve stability, particle size measurement and scanning electron microscopy (sem) results.
