摘要/Abstract

摘要： 以Y_2O_3 和Nd_2O_3为原料,采用溶胶-凝胶燃烧法制备出Nd:Y_2O_3激光陶瓷纳米粉体.XRD测试结果表明粉体的最佳煅烧温度为1000 ℃,并且晶化完全.原子力显微镜观察结果表明粉体的粒度约为200 nm,分布均匀.差热-热重分析表明,柠檬酸在447 ℃分解放热, 而晶型转变温度为590 ℃,荧光光谱测试表明粉体最强的荧光发射峰位于9421.646 cm~(-1)(即波长1061.4 nm处) ,是 Nd~(3+4)F_(3/2)-~4I_(11/2)谱相导致的荧光发射.

Abstract: The Nd:Y_2O_3 laser ceramic precusor was prepared by sol-gel combustion method, and Y_2O_3 and Nd_2O_3 were used as raw materials.XRD analysis showed that the optimum calcined temperature of precursor was 1000 ℃. At the same time crystallization was completed.The analysis of DTA-TG indicated that the citric acid was decomposed at 447 ℃,and the temperature of crystal inversion was 590 ℃.The strongest fluorescence peak of Nd:Y_2O_3 laser ceramics precursor was 9421.646 cm~(-1), that was Nd~(3+4)F_(3/2)-~4I_(11/2).
