摘要：
Photoluminescence (PL) of ZnCdO alloy with medium Cd concentration (50 wt %) is studied at different temperatures and at varying excitation intensity. The PL peak position shows red-blue-red (S-shaped) shift with increase in temperature due to potential fluctuations on alloying. The line width of PL profile shows increasing-decreasing-increasing behavior with increase in temperature. The dependence of S-shape behavior on Cd concentration is analyzed.
