摘要：

Optical homogeneous linewidths of the P03-H43(1) transition of Pr3+ in BeF2 and GeO2 glasses reveal an anomalously smooth quadratic dependence on temperature from 8 to 300 K. The low-temperature behavior is consistent with a recent model of Lyo and Orbach involving an interaction with a single two-level system but the smooth quadratic behavior at all temperatures has deep consequences for the relative roles played by the ordinary phonons and the two-level system in line broadening. © 1979 The American Physical Society.
