Luminescence spectra of Cr3+ ions, contained in traces in some mixed sodium-cadmium β-alumina crystals, were taken at temperatures of 82 and 300 K. Linewidths and lifetimes of luminescence spectra are measured as a function of crystal composition over a wide range of sodium-to-cadmium ratios. The results provide a new confirmation of the cation distribution model, recently postulated to account for ionic conductivity and Raman data.

Linewidths and lifetimes of luminescence spectra are measured as a function of crystal composition over a wide range of sodium-to-cadmium ratios. The results provide a new confirmation of the cation distribution model, recently postulated to account for ionic conductivity and Raman data. |
