Absorption and luminescence spectra and decay curves have been measured at temperatures down to 12 K for 4ZnO-3B//2O//3 glasses doped with Pr**3** plus and Eu**3** plus . Analysis of the spectra has yielded information about the probability of the radiative transitions in the impurity ions and the strength of the electron- phonon coupling. The strongly non-exponential decay curves indicate the importance of energy transfer and migration processes accounting for the dynamics of the excited states of Pr**3** plus .
