After deposition, the films were annealed at previously confirmed conditions (400 \u00b0C\/4 h\/synthetic air) and further investigated by utilization of X-ray diffraction (XRD), X-ray reflectivity (XRR), energy-dispersive X-ray spectroscopy (EDS). The gas-sensing behavior was tested in the air\/acetone atmosphere in the range of 0.1\u20131.25 ppm, as well as at various relative humidity (RH) levels (10\u201385%).
