“…The sensors offer a large advantage in several fields such as industrial manufacturing, [ 1 ] aerospace, [ 2 ] bioengineering, [ 3 ] and protection of environment. [ 4,5 ] They are based on semiconductors like SnO 2 , CdO, ZnO, Co 3 O 4 , Mn 3 O 4 , WO 3 , and so forth. [ 6 ] Among them the TiO 2 material, this one gives us many possible applications such as photo‐sensors for detecting UV light, [ 7 ] biosensor for detecting biological substance, [ 8 ] virology‐sensor for rapid detection of SARS‐CoV‐2 (COVID‐19), [ 9 ] and gas sensor for detecting the pollutants gas.…”

Our TiO 2 thin films were elaborated using spray pyrolysis technique. The spray solutions were prepared by two titanium precursors: titanium (IV) propoxide and titanium chloride. The elaborated thin films were analyzed with different characterization techniques such as X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and UV-visible spectroscopy.These characterizations showed that the change of precursors from titanium chloride to titanium propoxide has a significant impact on all TiO 2 properties.The structural characterizations showed the formation of anatase TiO 2 and the crystallization improvement when the precursor changed from titanium chloride to titanium (IV) propoxide, which proves the superiority of our TiO 2 thin layers made without any type of annealing in comparison with other previous studies. The SEM images showed an improvement of the surface quality of the TiO 2 thin layers with the change of TiO 2 precursors' solution. The obtained optical properties confirmed the semiconducting properties of TiO 2 prepared by titanium propoxide with a large band gap equal to 3.28 eV and shifted to 3.18 eV. The refractive index increases from $1.75 to $2.14, while the porosity decreases. To confirm the experimental results, the Wien2K code, founded on the full-potential linearized augmented plane wave (FP-LAPW), has been used. The theoretical study has been done by applying the generalized gradient approximation (GGA), the modified Beck-Johnson (MBJ) exchange potential, and the local spin density approximation + Hubbard's parameter U (LSDA + U). The theoretical results varied with the variation of approximations. The obtained properties were improved with LSDA + U and acquired the real values of Eg, n, and k for anatase TiO 2 (like Eg = 3.214 eV). The obtained experimental and theoretical results could be considered superposable or better than other ones recently published.

“…The chromatography of gas and spectrometry of mass (apparatus of gas measurement) have been fabricated to quantify pollutant gases. [3] But unfortunately, these devices are inappropriate for continuous measure as they are difficult to use, and non-portable. Recently, low cost sensors founded on metal oxide semiconductors, are considered to be a good alternate to the conventional apparatus.…”

The semiconductor realization is a very significant stage in gas sensor application. Herein, the Mn3O4 semiconductor was deposited using chemical spray pyrolysis. The effect of deposition temperature on structural, vibrational optical and electrical Mn3O4 thin layers properties were investigated through: X‐ray diffraction, Raman spectroscopy, UV‐visible spectrophotometer, and two points electrometers respectively. The X‐ray diffraction showed the appearance of spinel phase of tetragonal Mn3O4 with strong formation direction along (101) plan and without any secondary phase indicating the formation of pure Mn3O4. The Raman spectroscopy confirmed the results obtained in XRD and certified the high‐quality formation of Mn3O4. In addition, the crystallinity improvement (the increase of crystallite size and the decrease of dislocation density) was caused by the increasing of deposition temperature from 350 °C to 450 °C. Optical properties such as transmittance, absorbance and band gap energy were extracted by UV‐Visible spectrophotometer. Thus, low transmittance, high absorbance and small band gap energy were observed at the highest substrate temperature (450 °C). The electrical conductivity showed good values between 4.83 and 13.89 mS.cm−1. These properties make Mn3O4 an appropriate material to be used as a sensitive layer in gas sensors applications.

Herein, the cobalt oxide thin films are elaborated by spray pyrolysis technique. The effect of temperature of substrates on several properties of cobalt oxide is studied. The thin layers are characterized by using X‐ray diffraction (XRD), Raman spectrometry (RS), and UV–vis spectrophotometer. The XRD analysis shows that Co3O4 thin layers have been formed along <111> preferential orientation. The RS displays the characteristic vibration modes of cobalt oxide phase, which confirms the formation of a single phase of spinel Co3O4 thin layers. The UV–vis spectrophotometer allows us to investigate the optical properties such as the absorbance, the transmittance, and the optical bandgap. The variation of electrical properties with the variation of temperature deposition confirms the high impact of the effect that study to make the cobalt oxide an important candidate for gas sensor devices.
