| 摘 要： | 关于对alkali lead borotellurite玻璃吸收光谱的研究具有重大的现实意义．采用点电荷模型，调节R1和R2的值，对alkali lead borotellurite玻璃中Cr^5＋的吸收光谱进行理论解释，计算了d-d跃迁，对实验结果的一些主要吸收峰进行识别，同时还计算了g因子．计算结果表明能级的理论值与吸收光谱的实验值以及g因子的实验值和理论值都符合的比较好．由此确定了alkali lead borotellurite玻璃中键长R1和R2．

| Abstract: | The research of the alkali lead borotellurite glass absorption spectrum is of great practical significance. This paper uses point charge model, adjusts the value of R1 and R2, to theoretically explain the absorption spectrum of Cr^5＋ in the alkali lead borotellurite glass, identifies some major peaks in the results of the experiment, and calculates d-d transition and g-factor. The results show that the theory of value and absorption spectra of the experimental data arc in line with each other. Thus we determine the bond length R1 and R2 in the alkali lead borotellurite glass. |
