In this work, the optical and electrophysical properties of tin dioxide thin films containing 1-5% La3+, obtained by oxidative pyrolysis, were studied using atomic force and Kelvin probe force microscopy, X-ray diffraction, and spectrophotometry. The films are optically transparent, homogeneous, and formed by crystallites 21-24 nm in size. The SnO2 film with 3% La3+ has the highest values of activation energy, roughness, and surface potential. Keywords: thin films, tin dioxide, activation energy, optical properties, transparency.
