Tin oxide nanosheets were crystallized on transparent conductive oxide substrates of fluorine-doped tin oxide in aqueous solutions. The nanosheets had chemical ratio of Sn:O:F = 1:1.85:0.076, suggesting fluorine doping into SnO2. They were hydrophobic surfaces with contact angle of 140°. They were c...
