In fact, electrochemical doping in colloidal dispersions also eliminates inter-NC LSPR coupling and can, in principle, reveal the physics governing LSPR modulation in individual NCs. Indeed, the LSPR shifts achieved through electrochemical doping of colloidal dispersions of Sn:In2O3 NCs are greater than those obtained in thin films of similar NCs. However, even in colloidal dispersions, there is partial offsetting of the individual NC trends due to the deposition of NCs on the electrode surface. In any case, the LSPR shifts obtained through chemical doping are 30-40% greater than those obtained through electrochemical doping of colloidal dispersions of 5 nm 10% Sn:In2O3 NCs (435 cm -1 ). The effective applied potential through CoCp*2 exceeds that which could be achieved by electrochemical doping without overly destabilizing the dispersion. The reduced pH during chemical doping lowers the energy of the bands, facilitating the enhanced electron transfer compared to electrochemical doping. Thus, while electrochemical doping and chemical doping are both capable of charging dispersed NCs, chemical doping is more efficient at producing large LSPR shifts, indicating that a high electron concentration is achieved.
