Abstract

Theoretically calculated emission and absorption spectra of InP/ZnS and InP/ZnSe/ZnS quantum dots (QDs) with the solution of Schrödinger’s equation on the basis of the strain-modified effective mass approximation (EMA) have been well matched with the experimental measurements. We also predict the emission and absorption spectra of InGaP-based quantum dots. The intensity of the emission peak wavelength of In_0.43Ga_0.57P/ZnSe/ZnS has increased more than 60% compared with that of InP/ZnSe/ZnS.
