Abstract: The production methods of semiconductor nanomaterials with new shapes and different compositions form the basis for the creation of high-performance structures in numerous applications. Kesterite structured materials are among these inorganic semiconductors and are suggested to be promising energy materials for the future. In this study, quaternary Ag₂MnSnS₄ nanocrystalline rods have been successfully synthesized for the first time by the colloidal hot-injection synthesis route and well-organized rod-like nanocrystals (NCs) with lengths ranging from 200 to 350 nm and widths from 10 to 30 nm were obtained. For this structure, the Ag₂MnSnS₄ exhibits a semiconductor property with a band-gap of approximately 1.3 eV. The optical properties and band-gap values were determined by UV-Vis absorption spectrum and using Tauc Equation. It has been observed that the Ag₂MnSnS₄ structure acquired by the proposed colloidal synthesis method can be an alternative to the commonly used materials based on Cd and Pb.
