Antimony doped SnO2 (ATO) films were prepared on glass substrates by spin coating method at rotational speeds from 2000 to 3500 rpm. The impact of rotational speed on physical properties of Sb-doped SnO2 films were reported. XRD profiles of Sb-doped SnO2 films exhibits tetragonal rutile phase structure. The surface morphology shows homogeneous growth of the films with spherical structure, and an agglomeration of grains was observed at higher rotational speeds. Sb-doped SnO2 films prepared at 3500 rpm show an optimum transmittance of 82 % at visible region. The optical bandgap energy of Sb-doped SnO2 films were increased from 3.23 to 3.46 eV due to Burstein–Moss (B-M) effect. The electrical resistivity of Sb-doped SnO2 films were increased from 2.80 · 10−4 to 3.86 · 10−4 Ω·cm with an increase of rotational speed from 2000 to 3500 rpm.

Пленки диоксида олова, легированного сурьмой (ATO), были получены на стеклянных подложках методом центрифужного нанесения при скоростях вращения от 2000 до 3500 об/мин. Исследовано влияние скорости вращения на физические свойства пленок Sb-SnO2. Рентгенограммы пленок Sb-SnO2 демонстрируют тетрагональную структуру рутила. Морфология поверхности показывает однородный рост пленок со сферической структурой, а при более высоких скоростях вращения наблюдалась агломерация зерен. Пленки Sb-SnO2, полученные при 3500 об/мин, показывают оптимальное пропускание 82% в видимой области. Энергия оптической запрещенной зоны пленок Sb-SnO2 увеличилась с 3.23 до 3.46 эВ вследствие эффекта Бёрстайна-Мосса. Удельное электрическое сопротивление пленок SbSnO2 увеличилось с 2.80×10⁻ ⁴ до 3.86×10⁻ ⁴ Ом·см при увеличении скорости вращения с 2000 до 3500 об/мин.
