Direct Preparation and Size Control of Highly Crystalline Cubic ITO Nanoparticles in a Concentrated Solution System

Highly crystalline cubic indium tin oxide (ITO) nanoparticles with narrow size distribution were successfully prepared directly in one step from a mixed solution of indium and tin salts by a solvothermal method with ethylene glycol as solvent. Also, size was easily manipulated by changing conditions, such as aging period and sodium hydroxide concentration.
