Transition of nanocrystalline In(OH)3 as spherical Indium Oxide nanoparticles embedded platelets

Indium oxide nanoparticles were synthesized by a co-precipitation method using the basic raw materials like Indium (III) Chloride and the precipitating reagent as Ammonium hydroxide. The formation of Indium oxide is highly dependent on temperature. The morphology, structural, particle size, optical and electrical properties of In2O3 nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive microscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared radiation (FTIR), UV spectra, Photoluminescence spectroscopic (PL) and Electrical resistance measurements. The results exhibit a crystalline cubic structure in particles, spherical shape, size about 14 nm and optical band gap of 4.20 eV.
