Super-resolution imaging and statistical analysis of CdSe/CdS Core/Shell semiconductor nanocrystals

Here we present a multifunctional algorithm. Firstly a super-resolution method is presented for optically imaging the spatial distribution of semiconductor nanocrystals with nanometre localisation. Secondly highly resolved multiple photoluminescence trajectories of hundreds of single semiconductor nanocrystals are obtained simultaneously. (a) Small region of a summed conventional wide-field image of single CdSe/CdS nanocrystals consisting of 3000 image frames. (b) Super-resolved image using the same image region of (a).
