Indium Phosphide Quantum Dots (InP/ZnS QD) 700 nm

Indium Phosphide/Zinc Sulfide (InP/ZnS) Core-Shell Quantum Dots, optimized for a 700 nm peak emission, offer a superior, heavy-metal-free solution for applications requiring deep-red to near-infrared (NIR) photoluminescence. These nanocrystals are meticulously engineered with a ZnS protective shell to ensure high quantum efficiency and robust chemical stability, effectively mitigating the surface oxidation common in phosphorus-based materials. As a safer, RoHS-compliant alternative to Cadmium Selenide (CdSe), these 700 nm InP/ZnS QDs provide a unique optical window where biological tissues exhibit lower autofluorescence and higher transparency.

Technical Properties

Applications

• Deep-Tissue Bioimaging: Enables high-resolution fluorescence imaging in the near-infrared window, allowing for deeper light penetration and reduced background noise in complex biological environments.
• Next-Generation QLED Displays: Acts as a critical deep-red component in high-definition displays, expanding the achievable color gamut and enhancing the saturation of red-channel pixels.
• Near-Infrared (NIR) Optoelectronics: Integrated into specialized photodetectors, optical fiber communications, and night-vision compatible displays where long-wavelength sensitivity is essential.
• Advanced Photovoltaics: Used in solar concentrators and multi-junction solar cells to capture low-energy photons, significantly boosting the overall energy conversion efficiency.
• Agricultural Lighting: Applied in specialized horticultural LED systems to mimic the "far-red" spectrum, which is vital for regulating plant growth, flowering cycles, and circadian rhythms.
• Biosensing and Assays: Serves as a stable fluorescent marker for diagnostic kits, particularly where interference from blood or serum autofluorescence must be minimized.
