Description
Summary:In this study, we report the synthesis and characterization of hybrid heterostructures composed of red carbon, an organic semiconductor polymer, and the perovskite (NH<sub>4</sub>)<sub>3</sub>ZnCl<sub>5</sub>. Red carbon was synthesized via the polymerization of carbon suboxide (C<sub>3</sub>O<sub>2</sub>), exhibiting strong light absorption and distinctive optical properties. The hybrid material was obtained by crystallizing (NH<sub>4</sub>)<sub>3</sub>ZnCl<sub>5</sub> in the presence of red carbon, leading to significant modifications in the optical characteristics of the perovskite. Comprehensive analyses, including X-ray diffraction, FTIR spectroscopy, UV-vis spectroscopy, and cyclic voltammetry, confirmed the formation of a type I heterostructure with enhanced luminescence and potential for advanced optical applications. The energy band alignment suggests that red carbon can function effectively as both a hole and electron transport medium. This work underscores the potential of (NH<sub>4</sub>)<sub>3</sub>ZnCl<sub>5</sub>@red carbon hybrid heterostructures in the development of next-generation optoelectronic devices, including sensors and LEDs.
