A theory of intrinsic radiative lifetimes of excitons in semiconductor quantum dots is presented. Simple closed-form expressions for the decay times are obtained for quantum dots fabricated from quasi-two-dimensional systems. In particular, the intrinsic temperature-dependent photoluminescence decay
Size-selective spectroscopic techniques and a tight-binding calculation with restricted configuration interaction are used to study the recombination and the relaxation of excitons in CdS quantum dots. The optical absorption spectrum is calculated and is found to be close to the experiments. The ana
