Abstract
Time-resolved resonant light scattering in a disordered system is theoretically investigated. It is found that pulse excitation enables one to observe directly the relaxation of elementary excitations which is caused by disorder. In the case of weak disorder, the rapid scatteringlike and slow luminescencelike components distinctively appear. In the case of strong disorder, a continuous change from scattering to luminescence appears, which reflects the dephasing dynamics in the excited states of a disordered system.Keywords
