摘要
Indium oxide (In2O3) nanoparticles were synthesized via a facile rapid sonochemical method. Detailed spectroscopic techniques were used to investigate optical, structural and chemical properties of the synthesized In(2)O(3)nanoparticles. The structural analysis shows that In(2)O(3)nanoparticles have cubic structure and are polycrystalline in nature. The morphology of the In(2)O(3)nanoparticles examined by field emission scanning electron microscopy revealed spherical and uniformly distributed particles. Bruno emit Teller surface analyzer demonstrated that the surface areas of In(2)O(3)nanoparticles is 45 m(2)/g and also confirmed that the synthesized nanoparticles are mesoporous. Raman spectra also revealed that the synthesized nanoparticles have cubic structure. In-O band stretching of the synthesized In(2)O(3)nanoparticles was confirmed using Fourier Transform Infrared Spectroscopy. Photoluminescence spectra of the In(2)O(3)nanoparticles showed broad and intense UV emission peak at 358 nm. Moreover, the synthesized In(2)O(3)nanoparticles showed good sensitivity and fast response toward the hydrogen gas at lower temperature.
