Abstract
Indium oxide nanoparticles of similar to 12 nm were synthesized by a simple chemical route using indium(III) nitrate. Nanoparticles are formed after calcining the dried precursor in air at 400 degrees C for 10 h. TEM analysis showed that the morphology and size of the In2O3 samples were affected by ultrasonication. FTIR and Raman studies reveal that the nanoparticles are single-phase cubic structure of In2O3. NEXAFS study was used to quantify the Indium and oxygen valence state. Magnetic behavior of indium oxide nanoparticles was found to be diamagnetic. UV spectra show a weak band at similar to 308 nm corresponds to optical band gap energy of 4.03 eV.
