In this paper, we report the observed triple luminescence peaks of InGaAsN/GaAs single quantum well (SQW) grown by metal organic vapor phase epitaxy (MOVPE). The triplet-peak was discovered by the photoluminescence (PL) measurement performed under low temperature. The saturation of PL-peak intensities at high excitation power suggests the transition of the lower-energy peak was dominated by fewer numbers of available states as compared to the higher-energy peak. The position of the higher-energy peaks remained invariant after rapid thermal annealing (RTA) treatments revealed that the responsible transition was attributed to effects not associated with incorporated nitrogen. In addition, a large blue-shift was observed for the lower-energy peak and was likely attributed to local nitrogen bonding transformation. As results of our observation, the PL spectrum of InGaAsN SQW is mainly composed of a cluster-induced emission peak and two planar-feature peaks.
