The old problem of the interpretation of the emission properties of Tl+ centers in alkali-halides is reconsidered in the light of recent experimental evidences relative to anomalous decay in the slow-emission component. A plausible interpretation, based on the Jahn-Teller model in its simpler version, is proposed considering the statistical dependence on the ensemble of the luminescence centers and the concurrent effect of the dynamical relaxation of the lattice.
Statistical-Dynamical Validity of a Jahn-Teller Model for Tl+ Luminescence
2002
Abstract
The old problem of the interpretation of the emission properties of Tl+ centers in alkali-halides is reconsidered in the light of recent experimental evidences relative to anomalous decay in the slow-emission component. A plausible interpretation, based on the Jahn-Teller model in its simpler version, is proposed considering the statistical dependence on the ensemble of the luminescence centers and the concurrent effect of the dynamical relaxation of the lattice.File in questo prodotto:
