| dc.description.abstract | he absorption spectrum of Cr3+ in BIGaZYTZr (30BaF2-18InF3-12GaF3-20ZnF2-10YF3-6ThF4-4ZrF4) fluoride glass is characterized by the presence of features on the 4T2g(4F) absorption band. These features result from interaction of the 2Eg(2G) and 2T1g(2G) sharp levels with the vibrationally broadened 4T2g(4F) quasi-continuum via spin-orbit coupling. We have analyzed this phenomenon in the frame of the Fano’s antiresonance model. This analysis permits us to determine the electronic structure of the chromium ion Cr3+ by the crystal field theory. A good agreement between the theoretical and the experimental energy levels are obtained. The fitted parameters by Fano’s antiresonance model and the crystal field parameters obtained in this work are compared with those of homologous fluoride glasses. | ar |
