Synthesis of 2D lead-free hybrid perovskites (CnH2n+1NH3BX4; B = Mn, Cu; X = Cl, Br, I) and characterization — •Irina Anusca, Adela Bronja, Martina Pantaler, Christian Fettkenhauer, and Doru C.

Organic-inorganic lead halide perovskites have a high content of toxic lead which may eventually hamper their commercialization [1]. 2D perovskites (CnH2n+1NH3BX4; B = Mn, Cu; X = Cl, Br, I) can be alternative classes of lead free perovskite for optoelectronic application. We prepare different series of Cu and Mn perovskites by mixing of different CnH2n+1 organic ammonium cation (alkyl and aromatic) and X halide ion and we studied the optical properties in such systems. Properties were analyzed using x-ray diffraction und UV-VIS spectroscopy.
