Shell-thickness-dependent photoinduced electron transfer from CuInS2/ZnS quantum dots to TiO2 films

(author unknown)



Jianhui Sun, Jialong Zhao, and Yasuaki Masumoto

We demonstrate the electron transfer (ET) processes from CuInS2/ZnS core/shell quantum dots (QDs) into porous anatase TiO2 films by time-resolved photoluminescence spectroscopy. The rate and efficiency of ET can be controlled by changing the core diameter and the shell thickness. It is found that ... [Appl. Phys. Lett. 102, 053119 (2013)] published Wed Feb 06, 2013.
