Far infrared up conversion phosphor

Infrared up conversion luminescent materials can store the energy excited by visible light or ultraviolet light, and then release the stored energy in the form of visible light when excited by infrared light. Its characteristic is that it can absorb infrared photons with low energy and emit visible photons with high energy. The luminous intensity of rare earth far-infrared up conversion luminous materials is two orders of magnitude higher than that of other similar luminous materials. It can be used for infrared laser detection board, anti-counterfeiting ink and plastic film. It can be combined with laser holographic anti-counterfeiting logo to play a comprehensive anti-counterfeiting role.

It is directly used in aqueous phase system and other polar solvent systems. After organic surface treatment, the product has high oil absorption and dispersion effect. It can be directly used in organic phase system and is suitable for preparing anti-counterfeiting ink.
