Effects of solvents and carrier gases on the electrical and optical properties of pyrosol-deposited SnO2-based films

摘要: Abstract SnO 2 -based films have been prepared by the pyrosol deposition method, and dependence of their electrical optical properties on solvent (CH 3 OH, H O) concentration in solution nature carrier gas (air, N ) has investigated. The resistivity obtained using air as decreases CH OH:H O mole ratio increases to 2–3, then with further increase ratio. transmittance exhibits a gradual decrease use always leads production much more resistive less transparent owing lower Hall mobility, but sharply increasing variations mobility function seem be good agreement changes surface morphology, which turn are well reflected X-ray diffraction analysis. These two experimental parameters governing total amount oxidizing agents included solutions appear also affect chemical composition films, influences not significant enough explain all properties.
