| Abstract: | The absorption and luminescence spectra of borate, phosphate, and silicate glasses and their dependence upon the activator concentration and the temperature were studied. The luminescence mechanism was investigated. The spectra were analyzed, taking into account the composition and structure of the glasses. The term scheme of the trivalent terbium in the glasses was constructed. The conditions for stimulated radiation in glass activated with terbium are outlined.Reported at the 12th Conference on Luminescence, L'vov, 1964. |
