FIG. 1.

PL spectra from SAQDs for various excitation power densities (indicated in near the spectra) at ambient pressure: (a) sample, (b) control sample. Spectra are normalized and offset for clarity. The lines which connect the peak maxima are guides to the eye.

FIG. 2.

Blueshift of the PL peak from SAQDs in the sample (open circles) as a function of the excitation power density at various pressures, which are indicated in kbar. The lines are guides to the eye. Data for the control sample at the ambient pressure (solid circles) are also shown

Image of FIG. 3.
FIG. 3.

Blueshift of the PL peak from SAQDs when the pumping density increases from as a function of pressure. Open and solid circles are for the sample and the control sample ( barriers), respectively. Dashed lines are guides to the eye.
