Abstract

The optical homogeneous widths of ions or molecules in glasses exhibit an anomalous behavior in both their magnitude and temperature dependence when compared to the same species in crystals. Many studies of the homogeneous widths of molecules have advanced our knowledge of properties such as low-temperature dephasing and spectral diffusion. However, the mechanisms of the homogeneous widths of ions in glasses are still not fully understood.
