摘要：

The time-resolved spontaneous emission from a disordered molecular monolayer is calculated using Green-function techniques. In addition to a fast-decaying transmitted and reflected coherent component in the forward direction, and a slowly decaying, incoherent, spatially homogeneous background, we predict a backscattering peak related to weak localization of excitons. Analytical and numerical calculations of the energy- and disorder-dependent cooperative radiative decay rate, the quantum yield of the coherent and incoherent components, and the exciton diffusion coefficient are presented.
