“…As far as from the literature concerned, there have been carried out lot of research work to enlighten the physical and chemical properties of rutile phase of tin oxide (SnO 2 ) [1,2]. Some of the most common applications of SnO 2 are: gas sensor [1,3], dye-based solar cell [4], oxidation catalyst [5], transparent conductor [6], and photo conductor [7]. Whereas, few reports has been cited to investigate the micro-structural and electrical properties of SnO [8,9].…”

Mg doped SnO thin films were fabricated via electron beam evaporator on the glass substrate. The XRD analysis showed that reference and Mg doped SnO thin films were consisted of tetragonal a-SnO phase with preferred directions along (101) and (002) orientations. It was observed that the intensity of the diffraction pattern peaks increased and crystallite size decreased with the Mg doping. Scanning electron microscopy showed that the needlelike particles having length in the range of 0.4-0.6 lm with a diameter of 0.1-0.2 lm are sintered together to form a compact structure of Sn 1-x Mg x O layer. In the Raman spectrum, two active mode (A 2u and E u ) were observed for Sn 1-x Mg x O thin films. The complex plot (Nyquist plot) showed the data point laying on a single semicircle and the dc resistance increases with the increase of Mg doping concentration.

“…Metal‐oxide semiconductor gas sensors are a basic technology for identification and measurement of the concentration of different gases and volatiles in a reliable way 8. Since metal‐oxide gas sensors react to a wide range of reducing and oxidizing gases, the selectivity and sensitivity of a sensor can be increased by optimizing a number of parameters, e.g.…”

We present pheromone measurements of metal-oxide gas sensors in a laboratory setup using a 'selective odorant measurement of a multi-sensor array'. The array was equipped with commercial gas sensors and measured with constant temperatures and a temperature cycle to increase the sensitivity. To compare and to calibrate the measurement of insect pheromones, we used a portable GC-MS with an electro-antennographic detection system for insect antennae. In order to reach a proof of principles for the intended use of the system for in situ analyses in viticulture and the development of a portable biosensor, we tested the sensors with the main component E7,Z9-Dodecadien-1-yl acetate of the pheromone of the grapevine moth (Lobesia botrana).

“…Tin oxides are widely employed in industrial applications, such as gas sensors, [1,2] dye-based solar cells, [3] oxidation catalysts, [4] transparent conductors [5] and photoconductors. [6] Commonly observed phases of tin oxides include rutile structure SnO 2 and litharge structure SnO corresponding to the tin oxidation states of +4 and +2.…”

aTin oxide nanotentacles were synthesized by combustion chemical vapor deposition in air. Their surface composition and optical properties were then investigated using X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. XPS core level spectra indicate that these nanotentacles are of high oxygen vacancy with chemical composition of about SnO 1.6 , which is also supported by the Sn Auger parameter. Besides SnO 2 , the optical properties of SnO were detected in Raman spectrum. Moreover, two new Raman peaks were found for the SnO 2 phase because of the high oxygen vacancy concentration.
