title: Extracting the average single-molecule biexciton photoluminescence lifetime from a solution of chromophores.
abstract: We present a method for obtaining the average single-molecule biexciton lifetime from an ensemble of chromophores in solution. We apply this analysis to a series of core/shell CdSe/CdS quantum dot heterostructures with increasing shell thickness and find that the lifetime of the biexciton increases with increasing shell thickness, consistent with a simultaneous measurement of biexciton quantum yield.
