Perovskite Quantum Dots Supplier - Alfa Chemistry

Compositional Engineering for Perovskite Quantum Dots


Alfa Chemistry is confident that we can provide our customers with high quality perovskite quantum dots for their optical research and energy development projects. We offer a full set of customized services for both pure and modified perovskite QDS to ensure that our customers get the downstream application research they need as soon as possible. At present, due to the limitation of traditional perovskite quantum dots, we can choose compositional engineering method to improve. This has been regarded as an effective technique that could not only adjust their optical properties and endow novel functionalities but also improve their stability.
