Perovskite Quantum Dots Supplier - Alfa Chemistry

Morphology Control


PbSe quantum dots have various morphologies, including PbSe nanocubes, nanorods, nanoflowers, star-shaped, branched and so on. The morphology of PbSe quantum dots can be adjusted by changing the types of surface ligands, adjusting the growth temperature, and using different lead sources and selenium source precursors. Alfa Chemistry is committed to providing corresponding services for the full range of quantum dots, and through professional teams and technologies, to provide customers with PbSe quantum dots with specific morphologies.


Alfa chemistry is at the forefront of quantum dot technology and can regulate the morphology of quantum dots to meet customer requirements. At the same time, the PbSe quantum dots synthesized by customers can also be tested for morphology. Customers can also perform morphological analysis of their quantum dots if they want. Our current services include the following:

  • Testing Services
  • Mechanism Analysis Service

Since the morphology of quantum dot is related to its performance, if the customer is not clear about the required morphology, please contact our customer service personnel in time, they will communicate with professional researchers to develop the most appropriate and feasible product solution for you. Of course, if you meet all kinds of questions during the product synthesis, you can directly send an email or put forward questions to us on the website, and our staff will deal with these information instruments to help you.
