摘要： 采用不可约张量法,分析了KTbP4O12晶体荧光光谱,拟合了五个晶场参量和八个相对论参量,结果与实验吻合。

Abstract: The irreducible tensor methods of ligand field theory has been applied to analyse the fluorescent spectrum of Tb (Ⅲ) in KTbP4O12The optimized parameters, 5 crystal field parameters and 8 relativistic parameters, were obtained based upon both the approximate C4v symmetry of the environment of Tb (Ⅲ) and the experiment magnitude of the spectrum. The result of calculation is agreement with experiment very well.
