Synthesis and characterization of nanosized ITO powders by glycothermal processing

Abstract

Nanosized ITO(indium tin oxide) powders were prepared in ethylene glycol solution under mild temperature and pressure conditions by precipitation from metal nitrates with aqueous potassium hydroxide. The average size and distribution of the synthesized ITO powders were about 20 nm and broad, respectively. The phase of synthesized particles was crystalline reacted at 230 degrees C for 6 h. The optical properties of the synthesized ITO powders were transparent.
