Description

The method of selective spectroscopy is used for analysing the kinetics of processes occurring under the conditions of excitation-energy exchange among activator centres of Pr3+-doped crystalline media, and typical peculiarities in the behaviour of ordered multicentred and disordered crystals are revealed. The approach to phonon density determination of multicentred and disordered crystals by Raman spectra data is suggested. (author)
