Near infrared absorption dye, absorption wavelength between 710nm-1070nm
Near-infrared (also called near-IR or NIR) dyes offer important advantages over traditional visible light 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.
