The prepared TMS nanomaterial underwent examinations with the X Ray Diffraction (XRD), UV-visible spectral (UV), Scanning Electron Microscope (SEM), Atomic Force Microscope (AFM), High Resolution Transmission Electron Microscope (HRTEM), Selected Area Electron Diffraction (SAED), Energy Dispersive Spectroscopic (EDS), and Vibrating Sample Magnetometer (VSM) techniques. The TMS material's structure was discovered by the XRD method to have a cubic structure, and the sample's particle size was calculated to be 22.651 nm. According to a SEM analysis, the sample contains particles that are somewhat agglomerated and have the shape of flowers. It has been determined from HRTEM and SAED tests that the nanoparticle is a single crystal. The EDS method was used to identify elements like Mn, S, and Sn. The band gap of TMS nanomaterial is estimated to be 3.42 eV by UV-visible spectral analysis and AFM investigation provides 2-d and 3-d pictures of the sample. According to VSM characterization, TMS nanomaterial is a type of paramagnetic material. The results of research using FTIR, thermal, fluorescence, cyclic voltammetry, and impedance to characterize tin-doped MnS (TMS) nanomaterial are evaluated.
