摘要：

Stationary and picosecond time-resolved luminescence spectra of confined excitons have been studied in nm-size CuCl microcrystals embedded in a NaCl matrix. Size-selective resonant excitation and the analysis including strong reabsorption effect make us possible to obtain the radiative decay time of the confined excitons. The decay time is found to be inversely proportional to the volume of the microcrystals. The size- and temperature-dependent radiative decay time is quantitatively interpreted on the basis of rapid radiative decay of the confined, coherent excitons in microcrystals as proposed by Hanamura. © 1990.
