Abstract

Abstract: ZnSe nanorods and ZnSe spheres were prepared with hydrothermal method, the products were characterized with XRD, TGA-DTA, SEM, the possible formation mechanism involving a co-growth process is proposed. The results show that the nanorod was formed approximately with the diameter of 50—100 nm and the length of 200—300 nm, the diameters of the spherical ZnSe ranged from 3 to 10 μm. The mixture of zinc blende and wultize structures of ZnSe nanorods could be obtained at reaction temperature of 240 ℃ and the zinc blende structure of ZnSe spheres could be obtained at reaction temperature of 210 ℃; The ZnSe nanorods/ITO film and spheres/ITO were sintered at 380 ℃ for 40 min. Photoelectrochemical properties of ZnSe nanorods and ZnSe spheres were studied. The maximum IPCE of ZnSe nanorods measured was 9.09%.

Key words: Hydrothermal method, ZnSe nanorods, ZnSe spheres, Photoelectrochemistry
