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.
