Abstract: This research article reports ITO and ITO+AgNO3 with different ratios (50 to 150 step 50) % have been that prepared by sol gel method. Its structural, optical, morphological, Topographical and sliding measurement is investigated. The prepared samples are characterized using different techniques like XRD, EDX, AFM, SEM and UV-Vis, analysis. From XRD found ITO films with cubic crystal structure. The X-ray diffraction (XRD) analysis of the samples indicates the absence of any silver or silver oxide compounds at 50% and 100% concentrations. However, at 150% concentration, the XRD spectra reveal the presence of two small diffraction peaks, which corroborate the existence of Ag2O and AgO. The mean crystal size is 44.1 nm, 14.38 nm, 14.33 nm, and 25.29 nm for the pure, (50 to 150 step 50) % samples, respectively. The EDX spectra indicate the existence of In, O, and Sn components in the deposited films. From SEM observed increasing the concentration of AgNO3 (50 to 150 step 50) % lead to result in any change in the morphology and particles size. Based on AFM images, it is clear that films containing only ITO and ITO+AgNO3 in varying proportions (50 to 150 50% steps) reveal the growth as sharp peaks distributed over the surface with average grain sizes of 70 nm, 40 nm, 60 nm, and 160 nm, respectively. The energy gap values fall dramatically from 4.49 eV to 1.9 eV as the mixing ratios of AgNO3 increase from 50% to 150%. The outcomes of the SA measurement. The sliding angle decreased from 73 to 46 degrees as the AgNO3 ratio increased
