We report the photoluminescence characteristics of molecular beam epitaxy grown GaInNAs/GaAs single quantum wells that emit near 1.5-m wavelength at room temperature. The photoluminescence properties were investigated by varying the excitation wavelength, excitation intensity and sample temperature. It is found that the spectroscopic properties in the 1.5-m material are quite different from those of similar GaInNAs/GaAs structures emitting at 1.2 m. The related radiative mechanisms in the 1.5-m samples are interpreted in terms of the optical transitions of phase-separated quantum-dot states rather than quantum-well states.
