摘　　要：信息的加密与防伪技术是当今信息安全领域中的重要研究内容,其中光学加密与防伪技术由于其并行性、高通量和低成本而倍受人们的青睐.本文主要综述了具有荧光防伪和加密功能的有机及纳米材料最新进展,主要包括室温磷光、刺激响应发光、上转换发光、激发依赖发光、单晶多色可调发光、多元防伪编码以及荧光寿命加密等,简要介绍了基于发光纳米材料的防伪油墨制备方法以及印刷工艺,提出了发光防伪与加密功能材料未来的研究方向.Due to the advantages of parallel processing, high-throughput and low cost, the optical information encryption and anti-counterfeiting technology have applications in information security and thus attract wide attentions. This review summarized the new fluorescent functional materials and encryption strategies, including long afterglow photoluminescence (PL), stimuli-responsive emission, up-conversion PL, excitation dependent PL, single crystal tunable multi-color PL, multi-level optical coding and PL lifetime encoding and encryption. Moreover, the preparation and printing process of anti-counterfeiting fluorescent inks have been discussed. Finally, the future horizon of information encryption and anti-counterfeiting functional materials was proposed.
