Abstract

Fluorescence microscopy has been used in conjunction with atomic force microscopy to study size-correlated emission properties of single oligo-phenylene vinylene-functionalized CdSe nanocrystals. Intensity trajectories of these composite nanostructures exhibit well-defined temporal recurrence times, which we analyze using FFT techniques. Size correlation microscopy reveals a roughly linear dependence of recurrence period on nanostructure diameter, which we interpret in terms of varying degrees of surface functionalization. Characterization and control of such fluorescence fluctuations is critical to incorporation of such composite systems into photonic devices.
