Preparation and characterization of organic-inorganic hybrid perovskite (C4H9NH3)2CuCl4

Organic-inorganic hybrid perovskite (C4H9NH3)(2)CuCl4 was prepared via the reaction between copper chloride and butylammoniam chloride. Its chemical structure was characterized by FT-IR and elemental analysis. Its thin film was obtained by spin-coating, and X-ray diffraction (XRD) measurements indicated the formation of two-dimensional layered perovskites structure, with the c-axis perpendicular to the substrate surface. The electronic structure, thermal properties and electrical properties of the hybrid perovskite (C4H9NH3)(2)CuCl4 were also studied by UV-vis, photoluminescience (PL), TGA, DSC, and Hall measurement.
