Enhanced formaldehyde gas-sensing response based on indium oxide nanowires doped with same-valence metal cations

Abstract

Mesoporous indium oxides nanowires (In2O3 NWs), Al-, Sb- and La-doped In2O3 NWs were synthesized with nanocasting method, and then the components, microstructures and morphology were characterized. All results indicate that...

Detection of ethanol gas at room temperature by In2O3-based screen-printed films fabricated through particle-free aqueous solution combustible inks

“…Indium oxide (In 2 O 3 ) is an n-type SMO, and it has excellent features such as low resistivity, broad band gap (3.5 to 3.8 eV), and high catalytic activity. The thin films based on In 2 O 3 have been employed as transparent conductive electrodes in numerous electronic and optoelectronic devices because of their decent electrical conductivity and exceptional transmittance in the visible and near-infrared regions [13].…”
