摘　　要：上转换发光材料是指能吸收多个低能量的长波辐射,经过光子加和之后发出高能量短波辐射的一类材料,这种独特的转换性质使其受到了人们越来越多的关注.综述了稀土掺杂上转换发光材料的制备方法,目前常用的方法有水热法、高温固相法、溶胶—凝胶法、溶剂热法、共沉淀法等,讨论了这些方法的优缺点.介绍了稀土掺杂上转换发光材料在生物领域、药物传输和生物成像、有色燃料废水吸附剂中的应用.最后对稀土掺杂上转换发光材料的研究前景进行了展望.Up-conversion luminescence material is the material that is able to emit a high-energy shortwave radiation by absorbing more long wave radiations and photon adducting and the unique properties of the material attract more and more people＇s attention. In this paper, the preparation methods of transformation on rare earth doped luminescence materials are summarized, such as, the current commonly used methods hydrothermal method, high temperature solid phase method, sol-gel method, solvent hot method and coprecipitation method. Meanwhile, the advantages and disadvantages of these methods are discussed. This paper also introduces the application of the material in the field of biological, drug delivery, biological imaging and colored fuel waste adsorbent. Finally, the research foreground of transformation on rare earth doped luminescence materials is prospected.
