Photoinduced electron transfer in novel CdSe–Cu₂Se type II core–shell quantum dots

Abstract

Herein we report the synthesis, characterisation and electron transfer studies of CdSe–Cu2Se QDs, a novel type II core–shell system.

Composite formation in CdSe:Cu2Se nanocrystal films, charge transport characteristics and heterojunction performance

“…[31][32][33] Ptype doping of CdSe with Cu 2 Se can tune the bandgap of CdSe for varying its optical response and this can improve the photocurrent conversion efficiency by providing extra holes. Simi et al 34 reported the synthesis of type II core-shell quantum dots by a high temperature organometallic method. They inferred that the charge separation in the CdSe-Cu 2 Se core-shell system makes it a good choice for designing light harvesting devices.…”
