Aspects of Single and Ensemble Nanocrystal Spectroscopy

Associate Professor and Reader, Chemistry School, University of Melbourne

3.30pm, Friday 15 October 2004, AR103 Seminar Room, Graduate Research Centre

In this talk I will discuss the factors that control the luminescence of small semiconductor nanocrystals. In particular I will focus on why the luminescence seems to be so variable. The data are consistent with surface states being the origin of both blinking and photobrightening. Methods for passivation will be discussed. Finally I will present some initial data from our group on single NC behaviour.
