Dependence of photoluminescence of ZnO/Zn(0.85)Mg(0.15)O multi-quantum wells on barrier width

Temperature-dependent photoluminescence (PL) from two multi-quantum well (MQW) structures with different barrier widths has been systematically investigated. The PL band in the well layers is dominated by localized excitons (LE), D(0)X, and D(0)X-1LO. As the temperature increases, luminescence from...
