Abstract

In this paper, synchronous fluorescence scan (SFS) spectroscopy has been applied for the first time for the simultaneous determination of a mixture of CdTe fluorescent nanocrystals (NCs) of various sizes without a pre-separation step. It is observed that synchronous fluorescence maximum correlates well with the size of the nanocrystals, i.e.; the λSFSmax is useful to determine size dependency of NCs. Synchronous fluorescence maximum along with the second derivative can identify individual NCs in a mixture in water. The method is found to be simple, sensitive, selective and fast for NCs determination in aqueous media.
