In a disordered MX-chain complex the self-trapped excitons exhibit nonexponential decay. The decay rate varies with energy across the luminescence band and depends on the photon energy of the excitation laser. This behavior is explained by the site selective generation of self-trapped excitons and their subsequent hopping relaxation.
