持久发光材料在停止激发后仍能继续发光，其储存的能量在持久发光后的衰减时间内逐渐释放，使得颜色和亮度变化缓慢衰减，对保护信息和打击伪造起到重要作用。当与其他防伪技术结合形成多模式、多流程的防伪设计时，完美隐藏真实信息，在防伪标识设计中具有广阔的应用前景。简要概述了三种不同的基于持久发光的单模态防伪应用的设计，以实现时间维度上的信息加密。研究陷阱中存储的能量在不同物理刺激下释放并应用于类刺激响应型长效发光材料，并基于双模态多种不同工艺设计长效发光防伪应用，获得动态防伪-多流程、多模式的防伪效果。本文回顾了近年来长辉发光材料在防伪领域的研究背景，比较了长辉发光材料应用于防伪研究的重要突破性进展，最后提出了当前存在的问题、未来的挑战和发展方向。

Anti-Counterfeiting Application of Persistent Luminescence Materials and Its Research Progress

Persistent luminescent materials can continue to emit light after stopping excitation, and their stored energy is gradually released during the decay time after persistent emitting, which makes the color and luminance changes in slow decay and plays an important role in protecting information and combating forgery. When combined with other anti-counterfeiting technologies to form a multi-modal and multi-process anti-counterfeiting design, it perfectly hides the real information and has a broad application prospect in anti-counterfeiting logo design. A brief overview of the design of three different persistent luminescence-based anti-counterfeiting applications in unimodality to achieve information encryption in the time dimension. The energy stored in the trap is studied to be released by different physical stimuli and applied to stimulus-like responsive persistent luminescent materials, and the design of persistent luminescence anti-counterfeiting applications based on many different processes in dual-modality, obtaining the dynamic anti-counterfeiting effect of multiple processes in multiple modes. This work reviews the research background of persistent luminescent materials in the field of anti-counterfeiting in recent years, compares the important breakthrough progress of persistent luminescent materials applied to anti-counterfeiting research, and finally puts forward the current problems, future challenges, and development directions.
