Notes:
Antimony-doped tin oxide (ATO) transparent conducting thin films were prepared bysol-gel dip-coating technique in the alcohol solution of metal salts of tin (II) chloride dehydrate andantimony tri-chloride. Usual glass slides (25×76×1mm3) were used as the substrates. As-prepared thinfilms were dried at temperature of 343K and annealed at temperatures of 673~823K. Their opticalproperties were analyzed by Hitachi U-3310 spectrophotometer. The good optical transmission of theATO thin films has been obtained as high as 80%-90% in visible region by the optimization ofdeposition conditions, but decreased substantially in IR region. From the X-ray diffraction (XRD)measurements, it showed that ATO films had the similar structures with the pure tin oxide films, i.e.tetragonal rutile structure, despite of some rhombic SnO crystals. We analyzed the transmittance inthe visible region depending on the vary Sb doped level, temperature, and dip-coating times. Thesheet resistance of the investigated thin films was determined by four-probe method, showing that itwas about 85-1009/□, which decreased with the increase of antimony doped concentration
