Abstract
The report is based on the kinetic and spectral-luminescence data studies of crystals and glasses doped with rare-earth ions. The recent data are discussed concerning the superiority of the high-multipole interactions ; attaining ordered arrangement of impurities in glasses by means of optical techniques ; revealing a diffusional stage of the donor-donor migration kinetics in a stochastic ensemble of the impurity centers.
