YNbO4粉末材料中Er3+发光研究及其光谱性质J-O计算
Luminescence Characteristics of Er3+ in YNbO4 Powder Materials and J-O Calculation of Its Spectrum
摘要
Abstract
In order to study up-conversion luminescence characteristics of Er3+/Yb3+ co-doped YNbO4 powder materials, the spectrum property was calculated by using J-O theory in this paper. The spec-trum intensity parameters were obtained by the fitting method based on the absorption peak’s area of the absorption spectrum, and the theoretical oscillator intensity and the experimental oscillator inten-sity were figured out according to the spectrum intensity parameters, and the mean square deviation of them (δrms ) was 3. 916 × 10 -7 . The parameters such as the transition probability, transition branching ratio and energy level life etc. of Er3+ particles in YNbO4 powder materials were calculat-ed, and the stimulated emission cross section of Er3+ radiative transition from the energy level 2 H11/2 , 4 S3/2 and 4 F9/2 to the ground state was also figured out. The experimental results show that YNbO4 is one kind of superior up-conversion matrix materials.关键词
