Cs_2NaAlF_6中掺Cr^(3+)的d-d跃迁的分析

The analysis of Cr^(3+) doped in Cs_2NaAlF_6 d-d transitions

对Cs2NaAlF6中摻Cr3+的吸收光谱的研究具有重大的现实意义.本文采用点电荷偶极模型,调节平均共价因子N和配体的电偶极矩μ,从理论的角度计算Cs2NaAlF6的d-d跃迁值,进一步识别了主要的吸收峰,区别了Cr3+占据Al(1)和Al(2)位的跃迁.结果表明实验值和理论值符合的比较好.

The research on the absorption spectrum of Cr3＋ doped in Cs2NaAlF6 has great practical significance.This paper uses point charge model,adjusts the average covalent factor N and the ligand dipole moment u,to calculate from a theoretical point the d-d transitions of Cs2NaAlF6,identify the main absorption peak and distinct the Cr3 ＋ occupying Al（1） and Al（2） transition.The results show that the experimental data and theoretical values are well matched.
