效应面优化模型获取Y4GeO8:Bi3+,Eu3+红色荧光粉掺杂浓度
Optimal Doping Content of Red Emitting Y4 GeO8:Bi3+,Eu3+Phosphor Designed by Response Surface Methodology
摘要
Abstract
Herein, a more direct method, response surface methodology, is used to predict the strongest red emis-sion of Y4 GeO8:Bi3 +,Eu3 + samples. The concentrations of Bi3 + and Eu3 + of the optimal sample were predicted to be 31. 03％ and 67. 36％(in mole ratio), respectively. The optimal sample was prepared and photoluminescent proper-ties were measured and characterized. Y4 GeO8:31. 03％Bi3 +,67. 36％Eu3 + has strongest red emission. The differ-ence between the intensity of experimental value and theoretical value is very small. The color coordinate of the as-prepared sample is (0. 6457, 0. 3490), which is very close to the color coordinate of standard red light (0. 6700, 0.3300). The luminous color of the sample is pure, and the calculated color purity reaches 98％. What's more, the internal quantum efficiency of the sample is as high as 72. 5％. In a word, this paper provides an approach for searching the optimal doping concentration of phosphors with the strongest luminescence directly, which can be used in exploring all types of co-doped phosphors.关键词
