Infrared upconversion phosphors pigment IR980nm
Infrared anti-counterfeiting materials in the absorption of 980nm band of invisible light, fast release energy, show bright color fluorescence effect, can convert various invisible infrared band beam into visible light.
When the light source removed, immediately stop emitting light, restore the original state of invisibility. -
UP-CONVERSION Phosphor Anti-Stokes Pigment
UP-CONVERSION Phosphor Anti-Stokes Pigment means that the material is excited by light of low energy and emits light of high energy, that is, the material emits light of short wavelength and high frequency after excitation of light of long wavelength and low frequency.

IR up-conversion phosphors 980nm
IR up-conversion phosphors are particles that convert infrared light into visible light. Normally, materials that fluoresce are down conversion particles that absorb energy at a higher level (ultraviolet) and emit energy at a lower level (visible). For example, typical ultraviolet lights will cause a visible fluorescence which is a shift down in photon energy levels.

Near Infrared (NIR) Dyes
Near infrared dyes show light absorption in the near infrared area of 700-2000 nm. Their intense absorption normally originates from a charge transfer of an organic dye or metal complex.

uv fluorescent invisible pigment
The fluorescent pigment is invisible to the normal light, it only glows bright in the light of the blacklight lamps. For maximum effect it is recommended to use UV lamps with a wavelength of 365 nm and transparent paints.
-
invisible security pigment
invisible security pigment also called uv fluorescent pigment，Ultraviolet fluorescent Pigment.
These pigments are neutral in color, with a white to off-white powder appearance. Not noticeable when incorporated into security inks, fibres, papers. When irradiated with 365nm UV light, the pigment emits fluorescent radiation of yellow, green, orange, red, blue and violet colors and so is immediately identifiable.
