Growth of Suzuki-like occlusions in KCl : Pb analysed by means of photoluminescence and absorption spectra

Abstract

A detailed analysis of the impurity-vacancy (I.V.) dipoles → Suzuki-like-phase (S.L.P.) conversion is performed by parallel I.T.C., optical absorption, photoluminescence (emission and excitation spectra and time decays) in KCl : Pb (concentrations ranging from 16 to 100 ppm) annealed at 215 °C for long times. The absorption and emission bands related to S.L.P. occlusions are identified. The kinetics of the process and possible energy transfer within the occlusions are discussed
