FIG. 2.

PL peak energy as a function of Bi concentration: experimental data (solid circles) and theoretical calculations (open circles). The solid line is a fit to the experimental data using a Bi concentration dependent bowing coefficient. The triangular symbols are the PL peak energies for samples with and 4.5% under maximum excitation intensity.

FIG. 3.

(a) Pump intensity dependence of PL peak energy for samples with various Bi concentrations and (b) effect of pump intensity on PL linewidth of . The solid line for the 4.5% sample in (a) is a fit to the data according to the model discussed in the text. Two lines with the same slope are plotted through the data for the 0.4% and 2.3% samples for reference. The inset shows a schematic energy level diagram for a alloy, with Bi localized states.
