Recombination dynamics of biexcitons in single semiconductor nanocrystals were studied using time-resolved second-order photon correlation (g⁽²⁾) measurements. Time-resolved g⁽²⁾ measurements and time-resolved PL measurements were simultaneously conducted. Using the results of the time-resolved PL measurements, the g⁽²⁾ curve was analysed for a time region dominated by the exciton emission. The ratio of biexciton quantum yield and exciton quantum yield extracted from other contributions such as charged exciton emission was estimated.
