“…Early research included the examination of a few manganese oxide specimens [3][4][5] and the morphological examination of manganese oxides derived from various precursors [6][7][8]. Manganese oxide shows a variety of oxidation states (+2, +3, +4) and crystal forms, including MnO, MnO 2 , Mn 2 O 3 and Mn 3 O 4 , which contribute to their effective gas sensing capabilities [9][10].…”

The work presents here the synthesis of pristine manganese oxide (Mn2O3) nanoparticles and magnesium (Mg) doped Mn2O3nanoparticles with the help of the chemical co-precipitation method. We have investigated the influence of Mg doping (9 wt%, 12 wt%, and 15 wt%) on the optical and structural properties of Mn2O3. The structural properties of undoped and doped Mn2O3 nanoparticles have been studied using X-ray Diffraction Spectroscopy (XRD). The numerous physiochemical bondings present within the prepared nanoparticles have been examined using Fourier Transform Infrared Spectroscopy (FTIR). Both photoluminescence (PL) and UV-Visible (UV-Vis) spectroscopy have been used to investigate the optical characteristics. All the measurements are done at room temperature. All of the samples’ absorption spectra have been investigated within the wavelength range of 200 to 800 nm. The UV-Vis absorption spectrum for pristine Mn2O3 nanoparticles shows a sharp peak at 289 nm. We have further determined the band gap of the prepared samples using Tauc’s equation. The pristine Mn2O3 exhibits a direct bandgap of 4.04eV. At an excitation wavelength of 320 nm, the prepared samples’ emission spectra have also been recorded.
