Abstract

Luminescence in ZnSe single crystals doped with isoelectronic Mg has been studied. It has been shown that Mg easily enters substitutionally on a Zn site forming Mg_xZn_{1 - x}Se mixed crystals with band-gap energy considerably larger than that of `pure' ZnSe. The photoluminescence spectrum of such crystals is dominated by blue and violet emission, the efficiency of which is higher than the efficiency of blue luminescence in `pure' ZnSe. Low voltage blue-violet electroluminescence with maximum emission at 2.98 eV at T equals 45 K and 2.875 eV at room temperature in Mg_xZn_{1 - x}Se mixed crystals has been demonstrated. What makes this material very promising for future application in constructing blue and violet light emitting diodes is discussed.
