摘要：

Photoluminescence（PL） test was conducted to investigate the effect of rapid thermal annealing（RTA） on the optical performance of self-assembled InAs/GaAs quantum dots（QDs） at the temperatures of 16 and 300 K. It was found that after RTA treatment, the PL spectrum of the QDs sample had a large blue-shift and significantly broadened at 300 K. Compared with the as-grown InAs QDs sample, the PL spectral width has increased by 44.68 meV in the InAs QDs sample RTA-treated at 800 ℃. The excitation power-dependent PL measurements showed that the broadening of the PL peaks of the RTA-treated InAs QDs should be related to the emission of the ground state（GS） of different-sized InAs QDs, the InAs wetting layer（WL）and the In0.15 Ga0.85 As strain reduction layer（SRL） in the epitaxial InAs/GaAs layers.
