Abstract


In this work indium tin oxide nanoparticles (ITO) have been synthesized by coprecipitation method with polyvinylpyrrolidone (PVP) as stabilizer. The effect of different molar ratios between PVP to indium and tin chloride on the particle size and crystallinety have been confirmed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). X-Ray diffraction results showed that the crystallinety of ITO nanoparticles decreases and the particles size increases from 12 to 20 nm by increasing the ratios of PVP to metal chloride solution from (1:2) to (2:1). Infrared absorption spectra indicated the chemical coordination between In or Sn to oxygen atom of carbonyl group. The TEM results showed that the ITO nanoparticles were well dispersed and uniform in cubic shape. The calculated optical band gap of ITO nanoparticles decreases by increasing the ratios of PVP to metal chloride solution. D.C. Conduction mechanism have been discussed.
