Abstract
Absorption and luminescence spectra and decay curves have been measure d at temperatures down to 12 K for 4Zn0-3B(2)O(3) glasses doped with P r3+ and Eu3+. Analysis of the spectra has yielded information about th e probability of the radiative transitions in the impurity ions and th e strength of the electron-phonon coupling. The strongly non-exponenti al decay curves indicate the importance of energy transfer and migrati on processes accounting for the dynamics of the excited states of Pr3.
