Abstract
Based on the polaron effect, we have provided a theoretical explanation for the photoluminescence (PL) spectra of a single InP/GaInP quantum dot, the characteristic features of which are a set of equally separated peaks and large linewidth. The phonon band required for our theory has recently been discovered as the disorder activated longitudinal acoustic band around 20 meV. Our theoretical predictions on the temperature dependence and the light polarization dependence of the PL spectra have initiated new experiments, which have confirmed our theory.
