Preparation of indium tin oxide (ITO) with a single-phase structure

Well-crystallized and nano-sized indium tin oxide (ITO) powders were prepared by a solvothermal process from a mixed solution consisting of indium nitrate and tin chloride. The characteristics of the solvothermally synthesized ITO powders were studied to investigate the contribution of the processing variables on the physico-chemical properties of powders. The results of this study show that the nano-sized blue ITO powders with a single phase could be directly obtained by changing the medium from water to organic solvent.

Indium tin oxide powder with an In to Sn mole ratio of 95:5 was successfully prepared from a coprecipitated In–Sn hydroxide gel by hydrothermal processing followed by calcination at relatively low temperatures (∼500 °C). Hydrothermal treatment of the In–Sn coprecipitated gel at 300 °C for 24 h led to the formation of a single phase of tin-doped indium oxyhydroxide (InOOH:Sn). Under hydrothermal conditions the oxyhydroxide phase appeared well crystallized with particles ∼80 nm in size. Calcination of the oxyhydroxide phase above 450 °C in air yielded a substitutional-vacancy-type solid solution of In2Sn1−xO5−y.

The synthesis of thin films of ITO (Indium Tin Oxide) is synthesized by thermal evaporation technique under high vacuum conditions and further annealing at different conditions of temperature. These films were further characterized by using SEM, XRD, AFM, photoluminescence spectroscopy and UV-Visible in order to understand the structural and optical properties associated with them. Parameters to synthesize uniform, homogeneous, single phase and highly transparent ITO thin films have been optimized.
