Abstract
Excitation and emission spectra and lifetimes of Mn2+ in cadmium chlor ide have been studied using the photoluminescence technique. A crystal -field analysis of the Mn2+ transitions by means of the model develope d by Curie et al. allowed us to determine the magnitudes for the relev ant crystal-field parameters as well as for the spin-transfer coeffici ents f(sigma) and f(pi). The different mechanisms involved in the rela xation of excited Mn2+ ions in the CdCl2 host crystal were obtained fr om the study of the thermal evolution of the Mn2+-emission lifetime.
