Structural, optical, photoluminescence, photocatalytic and antifungal features of Gd/Mn2SnO4 nanocomposite annealed at different temperatures

The present work describes comparative study of annealing temperature in the range of 500-900 degrees C on the successful synthesis of Gd/Mn2SnO4 nanocomposite via sol gel method followed by hydrothermal method. Structural, optical, photoluminescence, photocatalytic activities against methylene blue and methyl orange; and antifungal features against Aspergillus niger of Gd/Mn2SnO4 nanocomposite were studied. The structural and optical properties were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), fourier transform infrared spectroscopy (FTIR), UV-Visible spectroscopy and particle size analyzer (PSA) techniques. Crystallite size, particle size and optical band gap were calculated using XRD, PSA and Uv-visible spectroscopy, respectively. Gd/Mn2SnO4 nanocomposite annealed at 500 degrees C is found to be a competent photo catalyst for degradation of dyes used for the study and for the growth inhibition of Aspergillus niger.
