摘要
关于高稀土浓度化学计量比的稀土五磷酸盐晶体已为人们所熟知，国内外NdP_3O_(14)晶体已用作微小型激光器的工作物质。但对稀土五磷酸盐晶体的光谱参数报告得不多。
Based on Judd-Ofeld theory, the spectral intensity parameters are calculated, including oscillator strength parameters τλ spontaneous radiative transition probabilitiy, radiative lifetime, fluorescent branching ratioβ 0 and radiative quantum efficiency η etc. The sum of τλ parameters obtained from the linear relation of P=a∑λE+b are in agreement with those obtained by J-O method.
