非辐射DKR过程:理论的再探讨。IV。关于碱金属卤化物中F中心束缚极化子态的争论
Nonradiative DKR processes: revisiting the theory. IV. On the controversy over a polaron state bound to an F center in alkali halides
摘要:
我们正在评论的极化子状态绑定到碱金属卤化物中的F中心的早期假设。这些状态增加了色心的有效尺寸,它们在浓度依赖性现象中起着积极的作用,例如观察到的F中心发光的猝灭。我们的记录显示,只有一个相关的研究NaBr和NaI,这也是为了检查束缚极化子假说。对其他碱金属卤化物中浓度猝灭的进一步研究将使这一问题得到更好的解决。
英文摘要:
We are commenting on an earlier hypothesis of polaron states bound to F centers in alkali halides. These states increasing the effective size of the color centers, they play an active role in concentration-dependent phenomena, such as the observed quenching of F center luminescence. Our record shows only one related study on NaBr and NaI which has also been aimed at checking the bound polaron hypothesis. Further studies of the concentration quenching in other alkali halide hosts whould eventually shine more light on the problem.
