“…Furthermore, AZO films (see Figure 7 ) with different doping contents of Al were fabricated using fine-channel mist chemical vapor deposition (FCM-CVD) [ 65 ]. The precursor solution was synthesized via dissolving zinc chloride (ZnCl 2 ) and aluminum chloride hexahydrate (AlCl 3 ·6H 2 O) in distilled water.…”

With the continuous growth in the optoelectronic industry, the demand for novel and highly efficient materials is also growing. Specifically, the demand for the key component of several optoelectronic devices, i.e., transparent conducting oxides (TCOs), is receiving significant attention. The major reason behind this is the dependence of the current technology on only one material—indium tin oxide (ITO). Even though ITO still remains a highly efficient material, its high cost and the worldwide scarcity of indium creates an urgency for finding an alternative. In this regard, doped zinc oxide (ZnO), in particular, solution-processed aluminum doped ZnO (AZO), is emerging as a leading candidate to replace ITO due to its high abundant and exceptional physical/chemical properties. In this mini review, recent progress in the development of solution-processed AZO is presented. Beside the systematic review of the literature, the solution processable approaches used to synthesize AZO and the effect of aluminum doping content on the functional properties of AZO are also discussed. Moreover, the co-doping strategy (doping of aluminum with other elements) used to further improve the properties of AZO is also discussed and reviewed in this article.

“…This is ascribed to the structural deformations occurred by the amalgamation of Fe 2+ ions which substitutes the Mo 6+ ions from the host MoO 3 matrix [38]. The diminution in transmittance for Fe dopants (1, 2, and 4%) are due to the amplified scattering of photons originated by the crystal defects, where the voids are less compared to the Fe (3%) dopant concentration [39,40]. Figure 3 illustrates the Tauc's plot for obtaining the optical band gap (E g ) of the fabricated thin films MoO 3 :Fe (0, 1, 2, 3, and 4%) calculated using Equation (4) [41].…”

“…The increase in carrier concentration causes the narrowing of band gap as the concentration of Fe doping increases, which is related to the raise in film defects. According to the Burstein-Moss effect, as the carrier concentration increases from Fe (0 to 4%), the lowest energy state of the conduction band is filled with the electrons, thus a red shift is observed in the Fermi level while doping from Fe (0%) to Fe (3%), and a blue shift is observed for Fe (4%) film, due to the increase in band gap, as a result of the heavily doped Fe 2+ ion on the host MoO 3 [40][41][42][43].…”

MoO3 thin films are fabricated using nebulizer spray pyrolysis technique, which is doped with Fe at various concentrations of 1, 2, 3, and 4% for ammonia gas sensors application at room temperature. X-ray diffraction (XRD) study confirms the growth of the crystal by Fe doping up to 3%, nano rods shape morphology of the thin film samples observed by field emission scanning electron microscope (FESEM), reduction in bandgap is evidenced via UV-VIS spectrophotometer. Gas sensing study is performed using gas analyzing chamber attached with Keithley source meter. Since 3% Fe doped MoO3 sample displayed nano rods over the film surface which exhibits highest sensitivity of 38,500%, in a short period of raise and decay time 54 and 6s. Our findings confirms that the 3% Fe doped MoO3 films suitability for ammonia gas sensing application.
