Abstract Indium tin oxide (ITO) nanoparticles are synthesized by the two-degradation sulfide and liquid-phase co-precipitation method under the given conditions with solutions of InCl3⋅4H2O and SnCl4⋅5H2O in the presence of ethylendyamine. The sample powders were characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses after heat treatments. The SEM results show that the size of the ITO particles prepared by the co-precipitation method is decreased to 100 nm, whereas the size of the ITO prepared by degradation of sulfide increases to 1 µm after heat treatment. The XRD results reveal that the size of crystallite ITO particles is increased with increasing annealing temperature. Finally the intensity ratio of I400/I222 has an increase of 29.07% for ITO prepared by the co-precipitation method.
