Photoluminescence from Er3+ or Pr3+ ion-doped silica or ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) glass, excited by high-energy photos such as excimer laser photons, was investigated mainly through the temperature dependence. When there are two emission states whose energy difference is small, as in the case of 2H11/2 and 4S3/2 in Er3+ or the 1I6/3P1 mixing state and 3P0 in Pr3+, the luminescence from the upper state and that from the lower state are found to depend inversely on temperature. This indicates that the thermalization or thermal equilibrium of electrons between the two emission states occurs.
