摘　　要：二氧化碲(TeO2)晶体同时具有优异的声光性能和高自然丰度的130Te双b衰变性能,既可用于高性能声光器件,也可用于中微子与暗物质研究。近年来,这两方面的应用都对TeO2晶体的尺寸和质量提出了更高要求。本文简要介绍了TeO2晶体的结构与物理性能,综述了大尺寸、高质量TeO2晶体制备的研究进展以及该晶体在红外器件中的应用进展,最后展望了TeO2晶体的制备与应用趋势。TeO2 crystal has excellent acousto-optic properties and double β decay properties of high natural abun- dance of 130Te isotope. It can be used in high-performance acousto-optic devices and also for the research of neutrino and dark matter. Recently, the above applications raise the requirements for the size and quality of TeO2 crystal. Struc- ture and physical properties of TeO2 crystal are briefly introduced in this article, and then the recent progress on the preparation of large sized TeO2 crystal with high quality and its application in infrared devices are reviewed. Finally, its preparation and application in future of TeO2 crystal are discussed.
