The synthesis and characterization of Zn0.85Cd0.15O/ZnO multiple quantum wells (MQWs) by remote-plasma-enhanced metalorganic chemical vapor deposition are reported. The X-ray diffraction satellite pattern is consistent with the existence of the periodicity of the MQWs. The quantum energy levels were investigated by observing the blue-shift of steady-state photoluminescence (PL) peak at low temperature. PL lifetime in MQWs measured by the time-resolved PL decreases from 70 to 54 ps with decreasing Zn0.85Cd0.15O well width, indicating the enhancement of the exciton recombination in the well layer.
