摘要： 以双层点电荷配位场(DSCPCF)模型和不可约张量算符方法,用自编程序计算了三角对称TbODA晶体的配位场微扰能级,并对其偏振荧光光谱进行了理论归属,结果与实验相一致.与经典点电荷配位场(PCF)模型的计算结果相比,DSCPCF模型更符合实际.

Abstract: The coordination field perturbation energies of Tb3+ in single crystals of trigonal dihedral(D3) symmetry Na3[Tb(C4H4O5)3]·2NaClO4·6H2Oare calculated and the polar-ized luminescence spectra in the 7FJ→5D4(J=1～6) transition regions are assigned theoreti-cally. The results of the double-sphere coordination point-charge field (DSCPCF) model are in reasonably good agreement with the experimental observation and are superior to that of the simple static coordination point charge field(PCF) model.

Key words: Coordination field calculation, Spectral analysis, Rare earth complex, TbODA
