Abstract
In the present work, MnS thick films were fabricated on glass substrates using commercially available analytical reagent (AR) grade MnS nanopowder and the screen-printing technique. A homogeneous screen-printing paste was prepared by mixing MnS nanopowder with BCA and ethyl cellulose, in a 70:30 weight ratio. The printed films were dried under an infrared (IR) lamp for 30 min and subsequently annealed in a closed muffle furnace at 200 °C for 2 h. The structural, morphological and elemental characteristics of the prepared MnS thick films were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). XRD analysis confirmed the formation of the hexagonal wurtzite γ-MnS phase, with the diffraction pattern indexed according to JCPDS Card No. 40-1289. The average crystallite size of the MnS thick film was determined to be 86 nm using the Debye–Scherrer equation. SEM analysis revealed a continuous and fine-grained surface morphology with localized particle agglomeration and irregular surface cavities. EDX analysis confirmed the presence of Mn and S as the principal constituent elements, with measured concentrations of 63.75 wt. % Mn and 36.25 wt. % S. The results demonstrate that the screen-printing technique provides an effective route for the fabrication of structurally stable MnS thick films with well-defined elemental composition and characteristic surface morphology.
