We argue that low-temperature time-resolved fluorescence provides a tool to study level repulsion of states which reside at the Lifshits tail of the density of states and dominate the optical response. The repulsion results from quantization of levels, wave functions of which overlap well. We demonstrate that the fluorescence spectrum at selective excitation consists of a narrow peak at the excitation energy and a red feature which can be associated with the conditional distribution of the nearest level spacing of overlapping localized states.
