Characteristic tin oxide films were formed on transparent conductive substrates in aqueous solutions. Surface of the films consisted of ellipse‐shaped particles. Particle size in longer or shorter direction was about 300–400 or 200 nm, respectively. In contrast, middle and bottom area of the films were dense structures. Thickness was about 1150 nm. The film was single phase SnO 2 with a ‐axis orientation. The films had chemical ratio of O/Sn = 1.20–1.37 and F/Sn = 0.088–0.124, suggesting fluorine doping. Facile synthesis of tin oxide particulate films had advantages in ordinary temperature synthesis, water solvent process, and low‐environmental load.
