The defects in CdTe and CdSe nanocrystals were studied by comparing the photoluminescence spectra and cyclic voltammetry dependences, which enabled us to identify two main electron levels in CdTe and four in CdSe NCs. In CdTe nanocrystals these levels are: a hole trap at the energy EV + 0.5 eV and a...
