摘要
无机稀土发光材料在照明、显示、激光和生物医学等领域有着极其广泛的应用。对荧光性能的调控有利于拓展其在温度传感、防伪识别、光开关、光存储等领域的应用。传统的荧光调控方式包括设计核壳结构、改变材料成分控制晶体场、改变稀土离子的掺杂类型或浓度从而控制能量传递等。然而,这些调控方式难以实现荧光性能的可逆调控,限制了其实际应用。对比传统的调控方式,材料在电场、热场或光场等外场刺激下可产生变色效应,通过变色效应可以实现对其荧光性能的可逆调控从而扩展其应用。本文主要综述了在电场、热场和光场刺激下,无机稀土发光材料的变色效应对其荧光性能的可逆调控及应用。
Inorganic rare-earth luminescent materials are widely used in lighting,display,laser and biomedicine.The fluorescence modulation is beneficial to expand the applications in temperature sensing,anti-counterfeiting,optical switch,optical storage,et al.However,the traditional fluorescence modulation methods such as designing the core and shell structure,changing the material composition to control the crystal field,and changing the doping type or concentration of rare earth ions to control the energy transfer are difficult to achieve reversible modulation of fluorescence properties,limiting their practical applications.Compared with these traditional methods,the color of materials can change under external stimulation,such as electric field,thermal field and light field.The reversible fluorescence modulation based on the chromic effect could expand the applications.In this paper,the reversible modulation based on chromic effect under electric field,thermal field or light field stimulation in inorganic rare-earth luminescent materials and their applications were mainly reviewed.
