Functional Inks: NIR Absorbing Materials


Our proprietary CWOTM and LaB6 materials with a scattering array of plasmonic nanoparticles selectively and strongly absorb near-infrared light in the 800 to 1200 nm range.
Compared to ITO and ATO, these materials can attenuate near-infrared light with short wavelengths, which accounts for much of the heat energy of sunlight.
They are widely applied in applications that convert light into heat as well as in sunlight control filters for automobile and building windows.

CWOTM is a trademark for Sumitomo Metal Mining's near-infrared absobing material.
