Luminescence spectroscopy is a powerful tool to investigate the properties of semiconductor quantum dots (QDs). The interpretation of such measurements, however, is not straightforward. Individual QDs inevitably vary in their properties, which causes variations in the corresponding luminescence characteristics. Thus, a luminescence spectrum, or decay, of an ensemble of such QDs is a sum of a very large number of different signals emitted by individual QDs and there is simply no way to decompose the ensemble signal back into its individual components.
