Mn 3 O 4 :Co thin films were characterized using XRD, SEM, Uv–VIS and Raman spectroscopy. The XRD spectra showed that thin films had substantially Hausmannite crystal structure. The preferential orientation of the pure and 0.5 at.% Co doped manganese oxide thin films (Mn 3 O 4 ) was (002), but with increasing Co doping, it was detected that this preferential orientation shift towards the (211) plane. The absorbance, transmittance and optical band gap of the Mn 3 O 4 :Co thin films were determined using Uv–Vis spectroscopy and these properties of the thin films differed considerably due to cobalt doping. The optical band gap of pure Mn 3 O 4 thin films was 2.00 eV, but on the other hand, due to the Co doping this value increased before and then decreased slightly. Optical transmittance of Mn 3 O 4 :Co films increased from 60% to 72% with the effect of Co doping. A1g mode, which is the characteristic vibration peak of Mn 3 O 4 films, was confirmed for pure and doped Mn 3 O 4 thin films at a wavelength of 658 nm. © 2019 Elsevier Ltdenginfo:eu-repo/semantics/closedAccessDoping effectHausmanniteRAMANSemiconductorsSILARCobalt compoundsCrystal structureEnergy gapLimeManganese oxideOptical band gapsOxide filmsOxidesSemiconductor dopingSemiconductor materialsSubstratesX ray diffractionDoping effectsHausmannitesNanostructured thin filmOxide thin filmsPreferential orientationRAMANSILARSoda lime glass substrateThin filmsDoping effectHausmanniteRAMANSemiconductorsSILARCobalt compoundsCrystal structureEnergy gapLimeManganese oxideOptical band gapsOxide filmsOxidesSemiconductor dopingSemiconductor materialsSubstratesX ray diffractionDoping effectsHausmannitesNanostructured thin filmOxide thin filmsPreferential orientationRAMANSILARSoda lime glass substrateThin filmsarticle128212220
