Diamond-like carbon films were deposited by electrodeposition technique onto SnO2-coated glass substrates by using a mixture of acetic acid and water as electrolyte. The films are compact with quite smooth surface. Raman spectra showed two distinct broad characteristic peaks at similar to 1350 and similar to 1600 cm(-1). Shift in the peak position was found to depend on the microstructure of the films. XRD spectrum of the films indicated strong peaks for (1 1 1) and (2 2 0) planes located at 2theta = 43.9degrees and 75.2degrees, respectively. Band gap and refractive index of the films deposited at different voltage varied between 2.87-3.08 and 1.55-1.61 eV, respectively.
