Preparation and Photoelectrochemical Study of CdSe Nanorods with Different Structure Phases

Hao Yan

Abstract

CdSe nanorods with different structure phases were prepared by a hydrothermal method, and the products were characterized with TEM, SEM, XRD, TGA-DTA. The results show that the CdSe nanorod with zinc blende structure is formed at 200℃reaction temperature. At 240℃reaction temperature, the wurtzite structure CdSe nanorod can be obtained.The IPCE of the wurtzite structure CdSe nanorod film electrode is higher than that of zinc blende structure CdSe nanorod film electrode. The wavelength with the max IPCE value for the CdSe/PMeT composite film electrode appears as red shift.
