Abstract

Indium oxide (In₂O₃) nanoparticles have been synthesized by rapid sonochemical technique. The as synthesized In ₂O₃ nanoparticles have been characterized by XRD, Raman Spectroscopy, FESEM, EDX, DRS, I-V measurement. XRD analysis has showed that the In₂O₃ nanoparticles have single cubic crystal phase with highly crystalline nature. Moreover successful doping of In₂O ₃ was carried by different Sn ratio. The stoichiometry of Sn in ITO was comprehensively examined by EDX analysis. FESEM studies showed uniform morphology of In₂O₃ and ITO nanoparticles. Raman spectra further confirmed the successful doping of Sn into the indium oxide matrix. The optical properties of In₂O₃ and ITO nanoparticles were analyzed with diffuse reflectance spectroscopy, and the band gap was found to vary from 3.45 to 3.75 eV with different Sn dopant concentrations. I-V measurements of the In₂O₃ nanoparticles at different temperatures showed the semiconducting behavior. Furthermore, the synthesized In₂O₃ semiconductor nanoparticles exhibited reasonable sensitivity and fast response towards hydrogen gas.
