Giant exciton-light coupling in ZnO quantum dots

By Bernard Gil and Alexey V. Kavokin

Abstract

We investigate the strength of the coupling of the electronic states with the electromagnetic field in ZnO nanospheres, taking into account the retardation effect. We show that the coupling strength is particularly strong: the bulk properties are so enhanced that the radiative decay time can reach some 200 ps for quantum dot sizes of some 30 n
