Mechanisms of radiative and nonradiative recombination in ZnSe:Cr and ZnSe:Fe
Possible applications of ZnSe:Cr in optoelectronics are discussed. It is shown that 2+ to 1+ photo-ionization of chromium results in efficient pumping of Cr²⁺ intrashell emission and in energy up-conversion from green to blue. A distinct difference in efficiency of the energy up-conversion is obs...

| description |
Possible applications of ZnSe:Cr in optoelectronics are discussed. It is shown that 2+ to 1+
photo-ionization of chromium results in efficient pumping of Cr²⁺ intrashell emission and in energy
up-conversion from green to blue. A distinct difference in efficiency of the energy up-conversion
is observed between chromium and iron doped ZnSe samples. This difference we relate to a
very efficient Auger mechanism of photoluminescence quenching in Fe-doped samples. We further
demonstrate an anticorrelation of intensity of mid-infrared Cr emission and up-converted blue
emission of ZnSe.
