Electrochemical observation of the photoinduced formation of alloyed ZnSe(S) nanocrystals

A study was conducted to investigate the evolution of the specific features in the cyclic voltammetric curves of ZnSe nanocrystals (NCs) as a function of their photochemical treatment. The results demonstrate that cyclic voltammetry is a powerful method for probing surface states of semiconductor NCs as well as for monitoring the evolution of these states during photochemical processing.
