Indium Phosphide Quantum Dots (InP/ZnS QD) 525 nm

Indium Phosphide/Zinc Sulfide (InP/ZnS) Core-Shell Quantum Dots, characterized by a vibrant 525 nm green emission, offer an elite, cadmium-free solution for high-performance optical applications. By utilizing a sophisticated core-shell architecture, these nanocrystals achieve a high photoluminescence quantum yield (PLQY) and superior resistance to photo-oxidation, ensuring long-term stability in diverse environments. These 525 nm QDs are specifically engineered to meet the stringent demands of the "Green Gap" in optoelectronics, providing narrow emission linewidths that result in unparalleled color purity. Fully compliant with environmental regulations such as RoHS, they represent a sustainable alternative to heavy-metal-based semiconductors, combining high absorption cross-sections with excellent dispersibility in concentrations ranging from 25 mg/mL to 100 mg/mL.

Technical Properties

Applications

• Ultra-HD Display Technology: Serves as the primary green light-emitting component in QLED displays and TVs, enabling a wider color gamut and more lifelike color reproduction compared to traditional phosphors. 
• High-Resolution Bioimaging: Utilized as a bright, non-toxic fluorescent marker for cellular imaging, where its 525 nm emission provides excellent contrast against red-shifted background signals.
• Backlighting Units (BLUs): Integrated into liquid crystal displays (LCDs) to enhance the efficiency and color quality of the backlight, significantly improving energy conservation in mobile devices.
• Fluorescence Resonance Energy Transfer (FRET) Sensors: Acts as an efficient donor or acceptor in ratiometric biosensors for the real-time detection of chemical and biological analytes.
• Precision Optoelectronics: Employed in the fabrication of green laser diodes and high-speed light-emitting diodes where narrow FWHM (Full Width at Half Maximum) is crucial for signal integrity.
• Photovoltaic Enhancements: Used in luminescent solar concentrators to shift UV/Blue light into the green spectrum, optimizing the spectral match for various thin-film solar cells.
