Abstract We report on optical properties of epitaxial (Cd,Zn)O layers and multi-quantum wells grown by laser molecular-beam epitaxy on lattice-matched ScAlMgO4 substrates. Exciton-phonon coupling strength in (Cd,Zn)O layers estimated by temperature dependence of the excitonic energy was similar to that deduced in ZnO. Time-resolved photoluminescence studies were performed on the multi-quantum wells, which are almost perfectly lattice-matched (0.034%). Radiative recombination of excitoas exhibits a spectral distribution of times. We found that the radiative lifetime increases linearly with temperature, showing a two-dimensional feature of excitons in quantum wells.
