Detailed Product Description

 

UP-CONVERSION (Anti-Stokes)ANTI-COUNTERFEIT PHOSPHOR

 

Up-conversion Anti-counterfeit Phosphor is a luminescent material that converts different invisible infrared light into visible light. Making full use of technology advantage of Chinese Academy of Sciences, KPT is the first company in China that develop this product, the quality has achieved the leading level of the world. it has characteristic of sensitive response, rich glowing colors, long lifetime, easy test and the most important-- high safety and concealed ability, by using it, IR (infrared ray) beam can be efficiently detected, tracked, identified and proofread etc.

 

Up-conversion phosphor is suitable for various kinds of printing application, and will not have any worse effect while mixing with any types of inks. It's can be added in plastic, paper, cloth, ceramic, glass and solution etc. Laser pen or home appliance controller are selected to test this phosphor material.
