    • In bulk CuCl crystal the luminescence decay time of excitonic molecules was usually measured to be about half that of excitons under high density excitation conditions, reflecting the population equilibrium between the two quasiparticle states brought by frequent exciton exciton collisions. [,] In QD's, however, such collisions never occur between excitons isolated in different QD's, and thus the observed decay time (65 ps) represents the real lifetime of the excitonic molecule confined in a QD, which is of the same order as those in bulk crystal (30 70 ps). [, 79, 755,] On the other hand, the lifetime of the confined exciton is size dependent because of its coherent nature, ( Ref. 10), and thus should not be directly compared with that of the free exciton in bulk crystal (a few ns) which is governed by the polariton impurity scattering.
