Description

technical field

[0001] The invention relates to an infrared up-conversion marking material, which can emit visible light under the irradiation of infrared light and play the role of anti-counterfeiting and marking. The invention also relates to a preparation method of the infrared up-conversion marking material. Background technique

[0002] Infrared up-conversion marking materials use the characteristics of different absorption of infrared rays (800-1500 nanometers), detect or identify their imprints through instruments, and have no reaction under ordinary light irradiation, but under infrared light irradiation, they can be tested. signal or text. Compared with the widely used UV-excited luminescent marking materials, infrared up-conversion marking materials have complicated synthetic components, high technical requirements, and are difficult to imitate. Since the high-efficiency up-conversion material uses relatively cheap infrared lasers to realiz...
