摘　　要：本研究以Zn和Se为源物质,NaOH水溶液为反应介质,采用水热法在125～200℃下反应24～36h制备了ZnSe粉体。采用XRD,XPS,EDAX和SEM等方法测试了所制备样品的相结构、表面元素状态、化学组成以及表面形貌,并研究了粉体的半导体光吸收特性。所制备的粉体为立方闪锌矿型ZnSe,粉体的粒径随水热反应温度的升高和水热反应时间的延长而增大。所制备的ZnSe粉体对紫外区的光呈现明显吸收,其光吸收最强峰位在波长468.8nm附近。In this paper, ZnSe powders were prepared at 100 - 200℃ for 12 - 36 h by hydrothermal method with Zn and Se dissolved in NaOH aqueous solution as source materials. XRD, EDAX, XPS and SEM were used to characterize the structure, composition and morphology of the samples respectively. The optical absorption properties of the ZnSe powders were measured. The obtained powders were cubic blende ZnSe. The grain size of ZnSe powders increased with the increase of hydrothermal temperature and soaking time. The ZnSe samples showed steep optical absorption at wavelength of around 468. 8nm.
