ITO thin films containing 8% Sn by weight were successfully prepared by heat treatment at 500 ̊C in this study. The structural and optical properties significantly depend on the coating speed. From the XRD result obtained, the prepared ITO thin film has cubic structure, and (222) is its preferred plane. As the coating speed increase, films shows a lower degree of polycrystallinity. The grain size in the range nanometer decreased with increasing coating speed. The transmittance value of all ITO thin films are more than 90%. The band gap are calculated from plotting product of adsorption coeeficients in photon energy (̧›ớ„‌̧‘Đ2) against photon energy (hv) is in the range of 4.18 eV to 4.28 eV. The PL spectra decreases, as the coating speed increased.20aFaculty of Industrial Sciences and TechnologyxDissertations 0aUniversities and CollegesxDissertations 0aTheses
