Özet
Pure and metal (M) doped [copper (Cu), nickel (Ni) and iron (Fe)] $WO_3$ films have been produced on In:$SnO_2$ (ITO) slides by using facile chemical bath deposition and then annealed at 500 oC for 2 h. Structural, morphological, electrical and optical properties of the produced $WO_3$-based films were examined. Monoclinic $WO_3$ phase were observed in all the samples, and the peak intensities were decreased by metal inclusion with heterogeneous film growth on ITO substrate. Slight shifts from defect related emission peaks (blue and green) were observed in metal-substituted $WO_3$ samples from PL study. An optical band gap was observed to decrease in M:$WO_3$ samples. The surface resistance values were significantly reduced by metal additives compared to its pure counterpart, especially by the inclusion of nickel ions in $WO_3$. The results indicated that nucleus growth and thereby impurity/defect-related surfaces had a serious effect on the optical and electrical properties of M:$WO_3$ films.
