着重研究了经过不同氧化还原处理的不同掺杂及浓度的掺铁铌酸锂晶体的吸收边和透射谱 ,认为晶体的能带结构随掺杂离子及离子的价态变化而变化 ,并解释了吸收边的有关实验结果 .
The absorption edge and transmission spectra of different doped and concentrated lithium iron niobate crystals with different redox treatments are emphatically studied. It is considered that the energy band structure of the crystal changes with the valence states of the doping ions and ions, and is explained Absorb side of the experimental results.
