溶胶-凝胶法制备铒、镱共掺杂氧化钇
Preparation of Erbium and Ytterbium Co-Doped Yttrium Oxide
摘要
以Y2O3 、Yb2O3和Er2O3为原料，控制溶液的pH值为3~4，采用溶胶-凝胶法制备出Er、Yb:Y2O3多晶粉体。对所得到的粉体进行XRD测试，结果表明最佳煅烧温度为1 000 ℃,并且晶化完全。经过差热-热重分析表明，粉体在1 000 ℃煅烧后不再失重。荧光光谱分析发现，荧光发射的最强峰位于1 530 nm处，是Er3+ 4I13/2-4I15/2谱项导致的荧光发射。
Abstract
In this paper，Er, Yb∶Y2O3 polycrystalline powder is synthesized by sol-gel method with Y2O3 , Yb2O3 and Er2O3, and the pH value of the solution is 3~4. XRD analysis is shown that the optimum calcination temperature of precursor is 1 000 ℃. At the same time crystallization is complete.The analysis of DTA-TG indicates that the weight of samples is not reduced when it is sintered at 1 000 ℃. The strongest fluorescence peak of Er, Yb∶Y2O3 laser ceramics precursor is 1 530 nm ,that is 4I13/24-I15/2.
