Abstract
Single molecule optical spectroscopy (SMS) allows for the characterization of photoluminescence intensity and lifetime of a isolated colloidal semiconductor nanocrystal, which provide valuable information about its intrinsic structural defects and interactions with the external nanoenvironment. In this chapter, we describe the application of SMS for the study of photoluminescence blinking and photoinduced charge transfer in colloidal semiconductor nanocrystals.
