Room-temperature synthesis and CO₂-gas sensitivity of bismuth oxide nanosensors.

ABSTRACT: Room-temperature (27 °C) synthesis and carbon dioxide (CO₂)-gas-sensor applications of bismuth oxide (Bi₂O₃) nanosensors obtained via a direct and superfast chemical-bath-deposition method (CBD) with different surface areas and structures, i.e., crystallinities and morphologies including a woollen globe, nanosheet, rose-type, and spongy square plate on a glass substrate, are reported. Moprhologies of the Bi₂O₃ nanosensors are tuned through polyethylene glycol, ethylene glycol, and ammonium fluoride surfactants. The crystal structure, type of crystallinity, and surface appearance are determined from the X-ray diffraction patterns, X-ray photoelectron spectroscopy spectra, and high-resolution transmission electron microscop
