“…The lower binding energy component (O I ) was associated with oxygen in the oxide crystal, whereas the higher binding energy component (O II ) represented the oxygen ions in the oxygen-deficient regions. Oxygen vacancies usually form in oxide nanostructures manufactured using thermal evaporation in an oxygen-deficient environment [22]. The oxygen vacancy content in the crystalline In-Sn-O nanostructures was defined as an intensity ratio: O II /(O I + O II ).…”

In-Sn-O nanostructures with rectangular cross-sectional rod-like, sword-like, and bowling pin-like morphologies were successfully synthesized through self-catalytic growth. Mixed metallic In and Sn powders were used as source materials, and no catalyst layer was pre-coated on the substrates. The distance between the substrate and the source materials affected the size of the Sn-rich alloy particles during crystal growth in a quartz tube. This caused In-Sn-O nanostructures with various morphologies to form. An X-ray photoelectron spectroscope and a transmittance electron microscope with an energy-dispersive X-ray spectrometer were used to investigate the elemental binding states and compositions of the as-synthesized nanostructures. The Sn doping and oxygen vacancies in the In2O3 crystals corresponded to the blue-green and yellow-orange emission bands of the nanostructures, respectively.

“…As is well known, one-dimensional (1D) semiconductor-based heterostructures possess better physical and chemical properties than the homostructures because these heterostructures can modulate the intrinsic properties of the materials [1][2][3][4][5][6]. For example, depositing noble metals on the surface of semiconductors can facilitate electrons transferring out conduction band of the semiconductors after irradiation, thus further enhance photocatalytic, photosensing and photodetective properties [7,8].…”

“…Indium oxide (In 2 O 3 ), an important n-type semiconductor, has been extensively studied due to its advantageous features, such as significant large energy band gap (3.5-3.75 eV) [1], high electrical conductivity [2], excellent luminescence [3,4], and high optical transparency [5]. Accordingly, it has a wide range of practical applications, including optoelectronic devices [6], solar cells [7], field effect transistors [8], electric-double-layer transistors [9], Fabry-Perot resonators [10], thin-film transistors [11], bio sensors, and gas sensors.…”
