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.
