“…This could be related to the higher boiling points of e and d compared with those of a–c (in the range 275–283 °C as compared to 170–186.8 °C). The presence of different amounts of residual C (in all cases) and N (in 1e ) may be important as to modify the number and type of defects and vacancies in the structures and, consequently, the properties and potential applications of these films [ 1 , 2 , 15 , 16 , 17 , 19 , 20 , 29 ].…”

“…Moreover, ZnO doping allows tailoring its electronic and optical properties and may provide multifunctional materials with improved properties or even new ones with potential interest in other areas, for instance, dilute magnetic semiconductors (DMSs) for spintronics [ 1 , 2 , 4 , 5 , 6 , 7 , 8 ]. Besides, ZnO-derived nanomaterials, pellets and thin films are gaining relevance in a wider range of areas (i.e., agriculture and biomedicine [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]).…”

“…This is mainly due to their utility in electronics, optics, optoelectronics, engineering, and, especially, for the design of new devices (photodetectors, gas sensors and also biosensors, light-emitting diodes, transparent electrodes and transparent thin-film transistors, among others) [ 1 , 2 , 4 , 6 , 11 , 12 , 13 ]. It is widely accepted that they are the most promising candidates to achieve low-cost and non-toxic new devices suitable for novel and improved technologies [ 1 , 2 , 6 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ], (e.g., solar energy conversion) [ 17 , 18 ] and, therefore, they are becoming more and more popular.…”

Here we present comparative studies of: (i) the formation of ZnO thin films via the sol-gel method using zinc acetate dihydrate (ZAD), 2-methoxyethanol (ME) as solvent, and the aminoalcohols (AA): ethanolamine, (S)-(+)-2-amino-1-propanol, (S)-(+)-2-amino-3-methyl-1-butanol, 2-aminophenol, and aminobenzyl alcohol, and (ii) elemental analyses, infrared spectroscopy, X-ray diffraction, scanning electron microscopy, absorption and emission spectra of films obtained after deposition by drop coating on glass surface, and thermal treatments at 300, 400, 500 and 600 °C. The results obtained provide conclusive evidences of the influence of the AA used (aliphatic vs. aromatic) on the ink stability (prior to deposition), and on the composition, structures, morphologies, and properties of films after calcination, in particular, those due to the different substituents, H, Me, or iPr, and to the presence or the absence of a –CH2 unit. Aliphatic films, more stable and purer than aromatic ones, contained the ZnO wurtzite form for all annealing temperatures, while the cubic sphalerite (zinc-blende) form was also detected after using aromatic AAs. Films having frayed fibers or quartered layers or uniform yarns evolved to “neuron-like” patterns. UV and photoluminescence studies revealed that these AAs also affect the optical band gap, the structural defects, and photo-optical properties of the films.

ZnO nanoparticles (ZnO-NP) present innovative optical, electrical, and magnetic properties that depend on specific characteristics, e.g., size, distribution, and morphology. Thus, these properties are essential to address various applications in areas such as electronics, medicine, energy, and others. In addition, the performance of this ZnO-NP depends of their preparation which can be done by chemical, physical, and biological methods. Meanwhile, nowadays, the main interest in developing ZnO-NP synthesis through biological methods bases on the decrease of use of toxic chemicals or energy applied to the procedures, making the process more cost-effective and environmentally friendly. However, the large-scale production of nanoparticles by green synthesis remains a big challenge due to the complexity of the biological extracts used in chemical reactions. That being the case, the preparation of ZnO-NP using Moringa oleifera extract as an alternative biological agent for capping and reduction in synthesis was evaluated in this work. Then, the results based on the analysis of the optical and structural characterization of the ZnO-NP obtained by employing UV-Vis, DLS, zeta potential, XRD, ATR-FTIR, and FE-SEM indicate mostly the presence of spherical nanosized material with a mean hydrodynamic diameter of 47.2 nm measured by DLS and a mean size diameter of 25 nm observed with FE-SEM technique. Furthermore, in FE-SEM images a homogeneous dispersion and distribution is observed in the absence of agglutination, agglomeration, or generation of significant lumps of the ZnO-NP. The XRD analysis showed that heat annealing induced the crystallite size favoring their monocrystallinity. Those obtained data confirm the synthesis of ZnO-NP and the absence of impurities associated with organic compounds in the annealed samples. Finally, those results and low-cost production present to the synthesized ZnO-NP by this biological method as a useful material in several applications.

Electro-deposition approach was used to produce zinc oxide nanostructure thin films for switching applications in optoelectronic devices. The aqueous solution of zinc nitrate (0.1, 0.5 & 1.0 M) and potassium nitrate (1.0M) of pH 6 were prepared at 65°C with constant stirring and nanostructure of ZnO thin film was deposited onto indium doped tin oxide (ITO) coated glass substrates. The morphology and growth size of deposited nanostructure thin film was analysed by SEM. The structural information was examined using XRD spectrum, which suggested that the deposited nanostructure thin films were crystalline with wurtzite phase. FTIR results gave information about metal oxide (ZnO) bonds and optical properties that was supported by the synthesized nanostructure. The effect of potential and concentration of used salts on the growth of ZnO nanostructure was also studied. Therefore, current-voltage characteristics were measured and applied for the switching properties in optoelectronic devices.
