The spatial and temporal luminescence dynamics in an InxGa1-xN single quantum well was investigated by using near-field optical microscopy. The near-field photoluminescence (PL) revealed the variation of both intensity and peak energy in PL spectra. It was found that the PL peak energy increased with increasing excitation power in both the strong intensity region and the weak intensity region.
