Abstract
The authors investigate the effect of treating n-ZnSe substrates with boiling aqueous Ca(NO3)2 suspension on their electrical and luminescent properties. Base substrates were cut from bulk pure zinc selenide crystals grown from a stoichiometric melt by the Bridgman method. It was found that the Ca-doping of the substrates causes an almost complete “quenching” of the low-energy orange emission band with a maximum near ħωmax ≈ 1,95 eV and a significant increase in the efficiency of the edge blue luminescence band.
