Conductive and transparent thin films of F-doped SnO2 were deposited on soda lime silica glass by utilising the sol-gel dipping technique. The chosen composition of Sn: F in the precursor sol was in the range 99:1 to 97:3 (atomic ratio). The developed films were of cassiterite SnO2 phase. Resistivity of the films was V-type with increase of F content and passed through a minimum at Sn:F = 97.5:2.5. Visible transmission (89-50%) of the films was dependent on film thickness and its refractive index. Microstructure of the films indicated porous surface feature.
