Preparation of indium tin oxide nano-sized particle and conduction film used as display material

摘要

The present invention is indium tin oxide (ITO) nanoparticles and the display element for the conductive film in the production process in about that, more specifically, the prior art compared to a low temperature and low pressure in the expensive crystalline ITO nanoparticles and a display element for the conductive film of the can be mass produced, and to other functional nano material can be applied to the manufacturing process provides a method for producing an electroconductive film for a high ITO nanoparticles and economical display device. ; Production method of the ITO nanoparticles according to the present invention comprises the steps of applying the indium precursor and tin precursor in a solvent; Adjusting the pH to 7 to 11; It includes; and heat-treating at a temperature of 100 to 350 ℃ and pressure of 10 to 80 atm.
