Synthesis of Nd:Y_2O_3 Laser Ceramic Nano-powders by Sol-gel Combustion Method

Abstract

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).

Key words: Nd:Y_2O_3;laser ceramic;Sol-gel combustion method
