Zinc Selenide Quantum Dots (ZnSe/ZnS QD)

Nanografi presents high-quality Zinc Selenide Quantum Dots (ZnSe/ZnS) tailored to suit specific requirements.

What are Zinc Selenide Quantum Dots?

Zinc Selenide/Zinc Sulfide (ZnSe/ZnS) Quantum Dots are semiconductor nanocrystals engineered with a ZnSe core and ZnS shell. They provide tunable emission in the blue region of the visible spectrum (430 nm and 450 nm), delivering high color purity, narrow emission bandwidths, and improved stability. Their core–shell architecture reduces surface defects and enhances photoluminescence efficiency, making them suitable for integration into optoelectronic devices.

Synthesis and Applications of ZnSe/ZnS Quantum Dots

ZnSe/ZnS Quantum Dots are synthesized using colloidal methods that allow precise control of particle size and emission wavelength. The ZnS shell improves quantum yield and photostability, while surface ligands enable solubility in organic systems. ZnSe/ZnS QDs are widely applied in QLED displays, optoelectronics, bioimaging, sensors, and energy research.
