Parameters and mechanism of elementary interaction of the electronic excitation of rare-earth ions with the local impurity oscillations
The parameters of elementary nonradiative energy transfer of the electronic excitation of rare-earth ions to the local impurity oscillations of the hydroxyl groups in inorganic glass dielectrics were determined by accurately measuring the kinetics of luminescence in a wide dynamic range of intensities. An anomalous temperature dependence of the transfer probability was observed. It is shown that the theory of ion-ion energy transfer can be used to describe quantitatively the observed effects of ion-vibrational transfer.
