Nonradiative DKR processes: revisiting the theory. I. Unimode model
摘要:
我们重新讨论了可极化固体中局域电子中心处DKR非辐射跃迁的效率问题。在简要的综述之后,我们制定了一般的速率方程,从而定义了控制非辐射去激发的微观参数。我们还重现了能量守恒的“水平转移率”的量子力学表达式,并与不同电子振动能级下的“垂直转移率”进行了比较。
英文摘要:
We are revisiting the efficiency problem of DKR nonradiative transitions at local electronic centers in polarizable solids. Following a brief survey, we formulate the general rate equations thereby defining the microscopic parameters controlling the nonradiative deexcitation. We also reproduce the quantum mechanical expressions for the energy conserving "horizontal transfer rates" to compare with the "verical transition rates" at various vibronic energy levels.
