Definitions
- the present invention relates to a method for the preparation of a stable suspension of metal oxide nanoparticles, designed for minimization of contamination of final products fabricated from these suspensions with non- volatile impurities at relatively low temperatures processing.
- the first reaction is a keto-enol equilibrium catalyzed by water and iodine, followed by the second reaction between the enol-acetone and iodine, giving H + ions and F ions.
- the indium-tin oxide nanoparticles were charged positively due to protons (H + ion) adsorption, thus during EPD they moved towards the negative electrode, i.e. cathode.
- the prepared suspension was stable at least several months, and high quality nanoporous indium-tin oxide films of controlled thickness were obtained.
