Description
Lead Sulfide Quantum Dots (PbS QDs) – 850 nm
Lead Sulfide Quantum Dots (PbS QDs) are advanced semiconductor nanomaterials distinguished by their size-tunable band-edge absorption and broad spectral response. With an emission peak at 850 nm (near-infrared region), PbS QDs exhibit remarkable photophysical and photoelectrical properties, making them highly valuable for both optoelectronic and biomedical applications.
One of the most important features of PbS QDs is their tunability: by adjusting the particle size, their absorption and emission wavelengths can be precisely controlled. This unique property allows for their integration into a wide variety of devices, ranging from infrared photodetectors to next-generation photovoltaics. PbS QDs also demonstrate strong quantum confinement effects, high carrier mobility, and long exciton lifetimes, enabling their use in cutting-edge energy conversion, imaging, and sensing technologies.
At Nanographenex, we supply high-quality Lead Sulfide Quantum Dots with consistent morphology and emission characteristics. Our PbS QDs are engineered to meet both research needs and industrial-scale requirements, ensuring reliable performance for diverse applications.
