本文报道了用发光光谱分析法测定三氧化二钇中微量铕,本方法采用的基质是三氧化二钇,并与硫氧化钇作基质的方法作了对比,两者的结果相近,但三氧化二钇基质法比硫氧化钇基质法有使用试剂种类少,操作简单的优点。文中还进行了荧光体的合成条件;发光光谱分析线的选择;激发条件选择以及共存元素的影响和试样分析结果的讨论。 In this paper, we report the determination of trace amounts of europium in yttrium oxide by luminescence spectroscopy. The matrix used in this method is yttrium oxide and compared with yttrium oxysulfide as a matrix. The results of the two methods are similar. However, The yttrium matrix method than the yttrium sulfide substrate method has the use of reagent types, the advantages of simple operation. The synthesis condition of phosphor, the selection of luminescence spectrum analysis line, the selection of excitation conditions and the influence of coexisting elements and the discussion of the results of sample analysis were also carried out.
