    "abstract": "We have performed near-field spectroscopy and microscopy of the InAs/AlGaAs\nquantum-dot-based nanoclusters. It is observed that the photoluminescence\nspectra of spatially confined excitons in the nanoclusters is blue-shifted up\nto 20 meV as the power density is increased. In particular, the near-field\nphotoluminescence images have shown that excitons became spatially confined\ngradually from lower energy state (1.4150 eV) to higher energy state (1.4392\neV) as the excitation power is increased, which is indicative of the\nband-filling effect of semiconductor nanostructures.",
