Abstract

Abstract: CdSe nanorods(zinc blende and wulitize) were prepared via hydrothermal method. The CdSe nanorod was formed with a diameter about 100 nm and a length about 300 nm. The photoelectrochemical pro-perties of the CdSe nanorods/P3CT composite film electrode were investigated. The results show that the maximum value of photocurrent appeared at an electrode potential of -0.6 V. The maximum IPCE(13.5%) of the modified film electrode was lower than that of 17.7% CdSe nanorord film electrode. The p-n heterojunction was existed in the CdSe/P3CT composite film electrode.Because of the existence of p-n heterojunction, under certain condition the IPCE of P3CT modified CdSe nanorod was larger than that of CdSe film electrode in the whole long wavelength region(>410 nm).

Key words: Poly(3-chlorothiophene), CdSe/P3CT composite film electrode, Photoelectrochemistry
