Lead sulfide (PbS) QDs


PbS QDs of Mesolight have a larger Bohr radius, making it easy to prepare nanoparticles with significant quantum effects. Due to its excellent non-linear optical performance, suitable forbidden band width, the electronic energy band spans the infrared spectral region of750 ~ 1600nm, which exactly overlaps with the "communication wavelength", therefore, PbS quantum dots Solar cells and other fields are widely used. The near-infrared wavelengths emitted by PbS quantum dots have strong tissue penetration and biological imaging performance with low background and high resolution, and therefore, are widely used in the biological field. The PbS quantum dots synthesized by Xingshuo Nano's unique proprietary technology have excellent characteristics such as narrow particle size distribution, high color purity, near-infrared light emission, and good stability. They also have low cost and are easy for mass production.
