Abstract
The surface electronic properties of CdSe nanocrystallites have been p robed using low temperature and Zeeman spectroscopies. Fluorescence li ne narrowed spectra show dramatic changes between 1.75 and 10 K and al so as a function of applied magnetic field. These effects are attribut ed to the localization of the photogenerated charge carriers on the su rface. A simple model has been constructed to calculate the charge dis tribution within the nanocrystallite.
