โœฆ Synopsis

The radiative decay rates of the lowest electronic excitations in a semiconductor sphere (quantum dot) are calculated for various temperatures and radii. We investigate how the interplay of quantum confinement and lattice vibrations affects the nature of the single electron-hole eigenstates. Application is made to the interpretation of recent fluorescence experiments in CdS quantum dots.

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
