Abstract
We study the time-resolved resonant secondary emission spectra of CuCl quan tum dots in a NaCl matrix under two-photon excitation. The emission is clea rly decomposed into the luminescence and scattering components by means of their temporal behavior. By analyzing the obtained results, we show that th e dephasing process of the confined exciton has a considerably long correla tion time, indicating that the system obeys characteristic non-Markovian re laxation.
