Electrochromic Response Obtained from Quantum Dots. Incorporating nanocrystals into future electronic or optoelectronic devices will require a means of controlling charge-injection processes and an understanding of how the injected charges affect the properties of nanocrystals. Researchers led by Philippe Guyot-Sionnest from the james Franck Institute at the University of Chicago (Chicago, IL) have shown that electrons can be reversibly injected into the quantum-confined states of nanocrystals using an electrochemical potential. Thus, the optical properties of colloidal semiconduc
