详细
A function for the analysis of the non-exponential kinetics of photoluminescence decay of colloidal quantum dots at room temperature is presented. The function takes into account trapping and detrapping of photogenerated charge carriers with physically meaningful parameters (time constant, trapping and detrapping rate constants, and average number of traps per quantum dot). Its validity is tested by time-resolved photoluminescence spectroscopy experiments with drop-cast films of CdSe/ZnS core/shell quantum dots.
