Quantum Dots

What are Quantum Dots?

Quantum dots are semiconductor nanocrystals just a few nanometers in size, whose optical and electronic properties are governed by quantum confinement. By tuning their size and composition, their emission wavelength can be precisely controlled across the visible and near-infrared spectrum, making them ideal for displays, bioimaging, sensing, and photovoltaics. These size-dependent fundamental principles of quantum confinement earned the field a Nobel Prize and continue to drive innovation across science and industry.

Types of Quantum Dots

• Cadmium Selenide Quantum Dots (CdSe/ZnS)
• Zinc Selenide Quantum Dots (ZnSe/ZnS)
• Indium Phosphide Quantum Dots (InP/ZnS), cadmium-free
• Lead Sulfide Quantum Dots (PbS), near-infrared emission
• Carbon Quantum Dots (CQD)
• Graphene Quantum Dots (GQD)
• QLED Quantum Dots for display applications

Features of Quantum Dots

• High photoluminescence quantum yield
• Size-tunable, narrow emission across visible and near-infrared
• Broad absorption spectrum for flexible excitation
• Excellent photostability and colloidal stability
• Core-shell structures for enhanced brightness and durability
• Cadmium-free options for safer, RoHS-friendly applications

Applications of Quantum Dots

Quantum dots are used across a wide range of advanced technologies, including QLED displays and lighting, photodetectors, sensing, and optoelectronic devices. Their tunable, biocompatible emission has opened powerful new directions in biomedical imaging, labeling, and drug delivery, while their efficient light harvesting is increasingly central to next-generation solar cell technology. This combination of high brightness and size-tunable emission makes them a key material for next-generation display, biomedical, and energy solutions.
