摘　　要：单一荧光模态稀土上转换荧光纳米材料存在防伪应用效果不佳的问题,对其发光模态进行调控,可实现对信息的多维度隐藏,提高防伪信息的复制难度,提升防伪应用效果,从而满足多场景的商品包装防伪需求。综述了近年来通过基质调节、核壳组装与复合异质荧光材料,实现稀土上转换荧光材料的多模态发光调控及防伪应用的研究进展,总结了推进该技术实际应用面临的挑战,提出了未来可能的发展方向。To address the issue of rare earth upconversion nanomaterials(UCNPs)with single fluorescence mode showing poor anti-counterfeiting effect,by modifying the emission mode,the multi-mode phosphors-based UCNPs were used to realize multi-dimensional hiding of information,to increase the difficulty of copying anti-counterfeiting information and to achieve high-level anti-counterfeiting applications in multi-scenario commodity packaging.The recent research progress were reviewed on the modification of multi-modal emission of UCNPs through matrix adjustment,core-shell assembly,or recombination of other phosphors and their packaging anti-counterfeiting applications.Furthermore,the challenges and research direction for promoting the commercial application of packaging anti-counterfeiting technologies-based UCNPs were also discussed.
