A method of producing ITO sol by Metal-Organic Decomposition processing

摘要: PURPOSE: A preparation method of nano-sized indium tin oxide(ITO) sol by metal-organic decomposition(MOD) is provided, which increases stability against moisture and enables produce thin films showing no cracks unlike conventional wet method. CONSTITUTION: The ITO prepared the following steps of: (S1) dissolving acetate C6H36Sn into 2-ethylhexanoic acid to be a In/Sn molar ratio 1.86 : 0.14; (S2) heating mixture at 200deg.C volatilize reaction product, acetic acid, stirring get transparent yellow from opaque mixed solution; (S3) adding hydrophobic solvent, 2-ethyl-1-hexanol, give moisture; (S4) aging formed over 5hrs concentrated sol.
