Optical properties including radiative quantum efficiencies, cross-relaxation coefficients, refractive index, energy-gap law parameters, and maximum phonon energy are presented for a new low-phonon-frequency, nonhygroscopic host crystal potassium lead chloride doped with and Assuming that the total decay rate (W) from each level is composed of radiative multiphonon and concentration-dependent cross-relaxation rates we determined radiative quantum efficiencies from emission data for five samples of various concentrations These results were compared with values calculated from a Judd–Ofelt analysis of the absorption spectrum. This technique required identification of cross-relaxation pathways. A cross-relaxation coefficient (where was measured for the
level. The measured multiphonon decay rates yielded energy-gap law parameters and indicating that laser action should be possible to near 9 µm in this laser host at room temperature.

Radiative lifetimes were determined as the ratio of the fluorescence lifetime to the radiative quantum efficiency
Determined from measured lifetime data with Eq. (21).
Assumed value.
Concentration dependent.
Assumed to be due to oxygen impurities in the host.
Samples 4 and 5 have been omitted from the average.
