Abstract: Double perovskite Ba 2 FeMoO 6 (BFMO) and doped with Ag ions were synthesized via the sol-gel method. The structural and antibacterial properties and viability of the samples were systematically investigated. The results of the Rietveld refinement indicated that both samples exhibited a single phase with cubic structure and space group Fm-3m. The substitution of Ag ions led to an increase in the unit cell and lattice parameters of BFMO, resulting in a change in the sample's morphology. The direct band gap (∼2eV) was measured for samples by Diffuse Reflectance Spectroscopy (DRS). Antibacterial activity of the Ba 2 FeMoO 6 and Ba 1.95 Ag 0.05 FeMoO 6 samples was assessed on the Gram-positive bacteria ( Staphylococcus aureus ) and the Gram-negative bacteria ( Escherichia coli ) using the spread plate method. The results showed that the samples were effective against Staphylococcus aureus but not against Escherichia coli . The sample doped with Ag ions showed a higher antibacterial effect than the pristine sample. An MTT assay of the normal fibroblast cell line treated with an Ag-doped sample showed a higher percentage of viability.
