Abstract
Dynamics of excitons and excitonic molecules in CuCl quantum dots are investigated by means of both time-resolved luminescence and transient absorption with use of sub-picosecond laser pulses. To explain the ex perimental results, a stochastic treatment by means of the Monte Carlo simulation and a rate-equation treatment are made, The former nicely explains the experimental results, while the latter does not. It is fo und that the exciton dynamics in CuCl quantum dots are characterized b y its stochastic nature due to discreteness of the exciton number in a quantum dot.
