Oil thermal annealed nano-structured indium tin oxide thin films for display applications

Indium tin oxide-coated thin films (200nm) are deposited on glass substrates by using R.f. sputtering technique. Here, we investigate the influence of new technique of treatment, which is called as oil thermal annealing on the nano-structured indium tin oxide thin films at fixed temperature (150 degrees C) which improves adhesion strength, electrical conductivity and optical properties (transmittance) of the films. Oil thermal annealing is used to reduce inherent defects that may be introduced during the prepared thin film and cooling processes. Proposed technique is highly suitable for liquid crystal displays, solar cells and organic light emitting diodes, and many other display-related applications.
