Enhanced Structural, Morphological and Optical Features of Tix MnNiO (X= 1, 2, and 3 mL) Synthesized Using Hydrothermal Approach

In this study, a hydrothermal method was used to synthesize Tix MnNiO nanostructures for photovoltaic applications. The synthesized films display a hexagonal phase and are polycrystalline. They exhibit a preferred alignment on the (111), (112), (116), (121), and (200) planes. The angles 2 theta are (26.612, 30.816, 32.154, 33.154, and 37.856) degrees. The structural properties of the material are enhanced by incorporating titanium into the lattice of manganese, nickel oxide. By integrating titanium into the MnNiO lattice, the material's UV absorbance was enhanced. At 310 nm, the noticeable peaks of the materials show a rise in titanium concentration, leading to enhanced absorbance during synthesis. The material absorbance decreases as the wavelength of light in the visible region increases. The indirect bandgap energy of the synthesized Tix MnNiO film decreases with increasing molar concentration, ranging from 2.75 eV to 1.82-1.50 eV.
