Abstract

In order to cope with the serious threat of fake and shoddy products to the social economy and the consumer rights and interests and develop a novel packaging anti-counterfeiting technology, the work aims to summarize the recent progress of up-conversion luminescent anti-counterfeiting materials and provide reference for the subsequent development and application of packaging anti-counterfeiting technology. The background and mechanisms of up-conversion luminescent anti-counterfeiting technology were briefly introduced, and the main preparation and characterization methods of up-conversion luminescent materials were introduced. Then, the latest research progress of up-conversion luminescent materials such as rare earth, carbon dots and organic materials were classified in detail, and their characteristics were analyzed one by one. The application of up-conversion luminescent materials in single-mode, dual-mode and multi-mode anti-counterfeiting was further discussed. Up-conversion materials have the unique advantages of multi-mode luminescence and anti-counterfeiting, but they still face the challenges of cost and environmental protection. In the future, it is necessary to make continuous breakthroughs in carbon point up-conversion and multi-mode integration to expand its packaging anti-counterfeiting application base.
