Indium Phosphide Quantum (InP/ZnS QD) Dots 600 nm

Indium Phosphide/Zinc Sulfide (InP/ZnS) Core-Shell Quantum Dots, optimized for a 600 nm bright orange-red emission, offer a superior and eco-friendly alternative to traditional heavy-metal-based semiconductors. These heavy-metal-free nanocrystals are specifically designed to meet the most stringent environmental regulations (RoHS) while maintaining exceptional optical and electrical efficiency. The InP core is meticulously encapsulated in a high-quality ZnS shell, which provides robust passivation of surface defects, leading to high photoluminescence quantum yields and significantly improved chemical and thermal stability. 

Technical Properties

Applications

• Cadmium-Free QLED Displays: Acts as a primary color conversion layer for eco-conscious televisions and monitors, enabling high brightness and wide color gamuts without environmental hazards.
• Safe Biomedical Bioimaging: Used as a non-toxic fluorescent probe for in-vivo and in-vitro imaging, allowing for high-contrast cellular tracking without the cytotoxicity risks associated with Cd-based dots.
• Next-Generation Optoelectronics: Integrated into high-speed photodetectors and transistors that require environmentally stable semiconductor materials with efficient charge carrier dynamics.
• Advanced Solar Harvesting: Employed in quantum dot sensitized solar cells (QDSSCs) and luminescent solar concentrators to enhance the absorption of the visible spectrum and improve conversion efficiency.
• Solid-State Lighting: Applied in specialized LED lighting to achieve precise warm-white color temperatures and high color rendering index (CRI) values.
