Abstract

Successive ionic layer adsorption and reaction (SILAR) method have been successfully employed to grow nanocrystalline Mn doped α-Fe2O3 thin films onto glass substrates. The structural analysis revealed that, the films are nanocrystalline in nature with rhombohedral structure. The optical studies showed that α-Fe2O3 thin film exhibits 3.02eV band gap energy and it decreases to 2.95eV as the Mn doping percentage in it was increased from 0 to 8wt.%. The SILAR grown α-Fe2O3 film exhibits antibacterial character against Staphylococcus aureus bacteria and it increases remarkably with Mn doping.
