Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom Organometal Halide Perovskite Quantum Dots


Perovskite is derived from a natural mineral rock substance, chemical formula is CaTiO3, the chemical formula is CaTiO3. The molecular formula of a typical perovskite compound is ABX3, A is usually a rare earth element or an element with a larger ion radius, B is usually a metal cation, and X is usually a halogen ion. The structure of organic-inorganic hybrid perovskite is a derivative form of traditional perovskite ABX3. B ions (such as Pb2+, Sn2+, Cu2+ and Bi3+, etc.) and X ions (X = Cl, Br, I) form a regular octahedron Structure, the A ion is an organic amine ion (such as Ch3Nh3+ or H2NCH2Nh3+), which is filled in the octahedral void by van der Waals force to form an organic-inorganic hybrid structure. Organic-inorganic hybrid perovskite quantum dots have the characteristics of low price, high carrier mobility and high light absorption coefficient. At the same time, due to the two excellent luminescence properties of perovskite materials, which are tunable wavelength and narrowband emission, it has good application potential in solar cells, electroluminescent LEDs, lasers and display screens. Alfa chemistry is committed to quantum dot services, providing customers with customized pure perovskite quantum dots, as well as modified perovskite quantum dots and product solutions.
