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. This review focuses on the research background and important breakthroughs in the field of persistent luminescent materials for anti-counterfeiting in recent years. It also comprehensively summarises the design of persistent luminescent-based unimodal and multimodal anti-counterfeiting applications, and investigates the release of energy stored in traps under different physical stimuli, obtaining the dynamic anti-counterfeiting effects of multiple processes in multiple modes.image
