Photoluminescence measurements have been carried out for Zn1-x Cdx Se:Co and ZnSxSe1-x:Co mixed crystals. Changes of recombination channels are observed in mixed crystals as compared to the emission of host binary compounds. Character of changes is slightly different for the alloys with cation and anion substitution. Photoluminescence kinetics of the L-line and of two other Co2+ intra-shell emission bands was measured to determine radiative decay rates. |
