中文摘要：
采用水热法制备了ZnSe纳米棒和微球，用XRD，TGA—DTA和SEM等技术对其进行了表征，提出了解释ZnSe微球的形成新机理．研究结果表明，纳米棒直径为50～100nm，棒长约为200～300nm，ZnSe微球直径为3～10μm．；纳米棒在反应温度为240℃时具有闪锌矿和纤维锌矿型7昆晶结构，微球在反应温度为210℃时具有闪锌矿结构；将ZnSe纳米棒和微球均匀地涂在导电玻璃的导电面上，于380℃煅烧40min后制成膜电极，并进行了光电化学研究，纳米棒膜结构电极最高单色光的光电转换效率（IPCE）可达到9．09％．
英文摘要：
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 rain. Photoelectrochemical properties of ZnSe nanorods and ZnSe spheres were studied. The maximum IPCE of ZnSe nanorods measured was 9.09%.
