A Comparative Study of Structural and Morphological Properties of Pristine and Mn Doped Ruthenium Oxide Thin Films.

Mn-doped and pristine Ruthenium Oxide composite nanostructures in thin film form were prepared on stainless steel substrates by sol-gel spin coating method. The at % of Mn was increased as 0.1, 0.2, 0.5, 1 and 2 %. The X-ray diffraction study showed crystalline behaviour for both pristine and doped films with porous morphology. The variation in lattice constants for both RuO2 and MnO2 was observed with increase in doping percentage. EDAX spectrum showed the successful doping of Mn in RuO2. The infrared spectrum of as deposited pristine RuO2 thin film depicted strong absorption bands at 880.41 cm-1 and 749.52 cm-1 indicating the stretching mode of Ru=O and O-Ru-O respectively. The absorption peaks attributed to the –OH bending vibrations along with Mn atoms were also seen
