High-Purity NIR Absorbing Dye NIR760P

Nichwell’s NIR760P is a premium, high-performance near-infrared (NIR) absorbing dye engineered to deliver a sharp, intense absorption peak at 760±3 nm.
Characterized by its exceptionally high molar extinction coefficient and minimal visible light scattering, this green powder dye is a critical functional additive for advanced optical engineering. It is widely specified by global formulators for invisible anti-counterfeiting security inks, IR cut-off filters, and transparent polymer compounding (PC, PMMA).
- Sharp & Narrow Absorption: Delivers a concentrated absorption peak exactly at 760 nm with remarkable near-infrared blocking efficiency.
- Broad Solvent Compatibility: Exhibits excellent solubility in a wide range of common organic solvents, making it highly adaptable for ink and coating formulations.
- Exceptional Stability: Maintains robust thermal and optical stability under extreme processing and environmental conditions.
- Low Fluorescence & Scattering: Ensures high clarity and precise optical signal conversion, crucial for sensitive NIR sensors.
- Polymer Integration: Flawlessly compatible with engineering plastics such as Polycarbonate (PC) and Polymethyl Methacrylate (PMMA) without compromising mechanical integrity.

Core Application Scenarios
Due to its unique spectral profile driven by efficient organic charge transfer, NIR760P is deployed across several high-tech sectors:
1. Security Printing & Anti-Counterfeiting Inks
Formulates seamlessly into invisible NIR security inks and varnishes. The printed markers remain completely invisible to the naked eye but yield a distinct, machine-readable signal under infrared detectors, safeguarding banknotes, tax stamps, and brand packaging against forgery.
2. Optical Filters & Displays
Acts as an indispensable component in IR cut-off filters for camera sensors (CMOS/CCD) and PDP displays, filtering out unwanted infrared interference while maintaining high visible light transmittance.
3. Functional Polymers & Smart Coatings
Easily compounded into Polycarbonate (PC) and PMMA matrices to manufacture smart greenhouse films, laser-welding plastics, and laser protection visors.
4. Optoelectronics & NIR Sensors
Utilized in organic thin-film ambipolar transistors and photodetectors for highly sensitive infrared signal absorption and electro-optical conversion.
