Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom PbS Quantum Dots


Custom PbS Quantum Dots

Alfa Chemistry is confident to provide the most suitable custom lead sulfide (PbS) quantum dots for customers' optical research and energy development projects with high-quality specifications. We have professional quantum dot researchers who can provide the most comprehensive service for the quantum dots you need in your project. The emission wavelength, size and quantum yield of quantum dots can all be customized for customers.


PbS quantum dots have the advantages of large Bohr radius (18nm), narrow band gap (0.41eV), symmetrical band structure, good photoconductivity, large dielectric constant, wide absorption spectrum and high absorption coefficient. One of the hot spots in the field of optoelectronic materials in recent years. The excellent optical performance of PbS quantum dots is mainly affected by the size of the quantum dots, and the range of the absorption spectrum can be adjusted by controlling the size of the synthesized quantum dots.


Alfa chemistry scientific team has a proven track record of success in the design, preparation, and characterization of different types of quantum dots. We help our customers choose and optimize the most appropriate method for each project. Our services include, but are not limited to the following:

While our company provides customers with quantum dots, it also has corresponding product test reports to ensure that the properties of the quantum dots you need are consistent. We will also have product after-sales service, if you have any questions, please feel free to keep in touch with us.
