Indium Phosphide Quantum (InP/ZnS QD) Dots 625 nm

Indium Phosphide/Zinc Sulfide (InP/ZnS) Core-Shell Quantum Dots, featuring a precise emission peak at 625 nm, represent the pinnacle of eco-friendly semiconductor nanotechnology. Engineered with a robust ZnS inorganic shell, these nanocrystals achieve superior quantum yields and exceptional photostability by effectively passivating surface defects and confining exciton energy. Unlike traditional heavy-metal-based fluorophores, InP/ZnS QDs offer a high-performance, non-toxic alternative that complies with global environmental regulations (RoHS). These dots exhibit a narrow emission FWHM (Full Width at Half Maximum) and a broad absorption profile, making them indispensable for high-purity color rendering and sophisticated electronic transitions.

Technical Properties

Applications

• Display Technology & Next-Gen LEDs: Used as highly efficient color converters in QLED displays to achieve a wide color gamut and vibrant red-light emission with minimal energy loss.
• Biomedical Imaging & Diagnostics: Provides a non-toxic, bright fluorescent probe for in vivo and in vitro imaging, allowing for deep-tissue visualization without the ethical and safety concerns of cadmium-based materials.
• Optoelectronics & Photonics: Integrated into high-speed photodetectors and thin-film transistors (TFTs) where precise bandgap engineering and efficient charge carrier dynamics are critical.
• Photovoltaics (Solar Cells): Enhances the spectral response of third-generation solar cells by harvesting a broader range of the solar spectrum and improving light-trapping efficiency through frequency down-shifting.
• Solid-State Lighting: Utilized in advanced lighting solutions to create "warm white" light profiles by accurately filling the red-gap in the visible spectrum while maintaining high luminous efficacy.
