| Abstract | ||||
| Spin-coating deposited transparent conducting MoO3 doped SnO2 thin films. MoO3 (0 ,7,10,12 and 15 wt.%) doped SnO2 thin films spin-coating deposited onto glass substrates at 550℃ were studied for their structural, optical and temperature dependent electrical behaviors. X-ray diffraction patterns revealed a tetragonal phase with polycrystalline structure. The XRD results confirmed decrease in crystallite size with increasing the MoO3 doping content. SEM was used to analysis of thin films revealed decreasing in spherical particle size. The samples ‘Composition has been analyzed using EDX. The UV-VIS-NIR spectroscopic investigation showed a reduction in visible optical transmission in addition to a significant decrease ten increase in optical bandgap by increasing MoO3 doping contents. Activation energy was calculated from temperature dependent electrical resistivity data measured in the range 370 to 460 K. The current showed that MoO3 doped SnO2 thin films are an attractive option for IR coating ,solar cells and other optoelectronic applications. | ||||
