Photoluminescence properties were compared between two types of multi-quantum-well (MQW) structures. One of them had a potential well layer composed of binary GaAs, and the other was composed of ternary AlxGa1-xAs. It is shown that the ternary well MQW structure is more favorable with respect both to higher emission energy and to photoluminescence linewidth than the binary well MQW structure.
