摘　　要：红光及远红光稀土荧光粉在LED植物照明中具有重要的应用前景,但由于稀土荧光粉存在制备复杂、跃迁禁阻、成本较高等问题极大影响该材料的应用前景。本文采用有机配体修饰Eu(III)发光中心,利用其天线效应提高稀土纳米片在近紫外和蓝光领域的吸收强度,改善发光强度;同时,将稀土材料制备成Eu(III)掺杂的氧化钇纳米片,大大增加了比表面积,增强了原子利用率,从而降低其成本;通过电镀时间可简单控制发光强度,实现经济、节能、环保、简便的稀土荧光薄膜制备技术。Red and far-red rare earth phosphors have an important application prospect in LED plant lighting,but the application prospect of rare earth phosphors is greatly affected by the complex preparation,transition resistance and high cost.The luminescence center(Eu(III))was modified by organic ligand,and the antenna effect was used to improve the absorption intensity of rare earth nanosheets in the near ultraviolet and blue light fields,which improved luminescence intensity.At the same time,the rare earth materials are prepared into Eu(III)-doped yttrium oxide nanosheets,which greatly increases the specific surface area and enhances the atom utilization rate,which reduced its cost.The luminous intensity can be simply controlled through the electroplating time,and an economical,energy-saving,environmentally friendly and simple preparation technology of rare earth fluorescent films can be realized.
