摘　　要：测得了光折变材料锰掺杂的钾钠铌酸锶钡晶体（ＫＮＳＢＮＭｎ）的透过率，给出了晶体的能态结构。按配位场理论讨论了Ｍｎ４＋的作用机制。The transmissivities of photorefractive material KNSBN∶Mn crystal have been measured, and its energy state structure is described. Based on the ligand field theory, mechanism and effect of the Mn ion on the photorefractive material KNSBN∶Mn are discussed and the optical diode effect is explained from the point of view of microstructure.

关 键 词：光折变晶体 透过率 D-D跃迁 铌酸锶钡
