Selective detection of methane and butane by temperature modulation in iron doped tin oxide sensors

Structural and optoelectronic properties of antimony incorporated tin oxide thin films

“…The Sb doped tin oxide (ATO) thin films are considered as an alternative to ITO and FTO due to its excellent heat resistivity [4]. Many dopants, such as W [5], Al [6], In [7], F [8], Si [9], La [10], Ni [11], Pt [12], Vd [13], Pd [14], Fe [15] and Sb [16] have been used to improve the electrical properties of tin oxide thin films. But in case of Sb doping, antimony presents a real challenge to electronic structure calculation in order to explain its optoelectronic properties [17].…”

Nanocrystalline gallium ferrite: A novel material for sensing very low concentration of alcohol vapour

“…For measuring the gas sensing properties, Taguchi type (tubular substrate around 3 mm length, 1 mm inner diameter and 3 mm outer diameter coated with the functional material and a heater core put inside the tube) were fabricated, the details of which are given elsewhere [17]. The fabricated sensors were aged at the working temperature before measurement in order to improve the stability.…”

Synthesis, characterization and low concentration ethanol sensing performance of sol–gel derived La(III) doped tin oxide

“…Kanthal heating coils were then placed inside the Al 2 O 3 tubes to produce the desired operation temperature. The detailed assembly [40] was shown elsewhere. Figure 1 depicted the outer and inner view of a fabricated sensor.…”
