“…In most reports published so far, it is obtained by using zinc acetate dihydrate (ZAD) as the salt and ethanolamine (EA) as the stabilizer. The increasing interest in the development of sol–gel ZnO inks is reflected by recent specific studies on the effect of solvents, , precursor nature and concentration, , EA/ZAD molar ratios, , sol aging, annealing duration, , annealing temperature, , and even specific process parameters such as withdrawal speed in deep coating on the properties of the resulting ZnO.…”

This work presents a detailed structural and chemical characterization of the system formed by zinc acetate dihydrate (ZAD) and ethanolamine (EA) with methoxyethanol (ME), in order to describe its stability. The origin of the mixture degradation during storage at room conditions is analyzed. Theoretical calculations of the frontier orbitals of the system ZAD plus EA under interaction with ME and CO 2 are used to deduce energy levels and stability of the different molecules appearing in the ZAD-EA-ME system. The models were tested as potential energy minimum and their photo-absorption spectra were simulated. The dimerization process leading from the simplest configuration to the most abundant one is also theoretically analyzed and used to describe the effect of the nuclearity raise on the mixture stability. Our results explain the experimental observations and provide a better understanding of the role played by EA in the formation of ZnO and, consequently, allow optimizing the technological processes to prepare these films.

“…The film thickness increased from 133 to 147 nm with withdrawal speeds from 3 to 5 mm s −1 . At fast withdrawal speeds, a larger amount of ink is pulled up in a relatively short time [33,35,36]. Due to the fast solidification of the ink, the pulled ink creates a thick solid film before moving back to the ink reservoir.…”

This study demonstrates a continuous high-resolution roll-to-roll (R2R) microcontact printing (µCP) process capable of printing inks on substrates with a wide range of surface energies. This process is based on rapid solidification of the fluoropolymer ink made up of a low boiling point solvent. The use of a hydrophobic siloxane polymer for the stamp allows film formation onto various substrates due to weak adhesion with the fluorinated polymer ink. To investigate its practical applicability the patterned layer printed by the R2R µCP was used as an etching resistant layer to pattern metallic and dielectric materials with 10 µm resolution. Moreover, the organic and oxide thin-film transistors with the patterned channels were combined to produce the hybrid complementary inverter circuits, having full swing transfer characteristics.

“…These advantages make the dip-coating an attractive method to fabricate ZnO thin films for many applications. Therefore, extensive studies have investigated the effect of different parameters on the ZnO film properties, such as deposition conditions, doping, and annealing, thereby providing a versatile approach for producing a wide range of ZnO-based materials [23][24][25][26][27][28][29].…”

In this study, four ZnO thin films were deposited on FTO substrates using the sol–gel dip coating method to examine their microstructural, morphological, and optical properties through various techniques. Three of them were subjected to ultraviolet (UV) light, magnetic field (MF), and a combination of UV and MF during deposition, referred as ZnO: UV, ZnO: MF, and ZnO: (UV+MF), respectively. The results obtained showed that the simultaneous UV and MF exposure improved the crystallinity and surface homogeneity of the as-deposited film. Moreover, ZnO: (UV+MF) film exhibited an average transparency of 80% in the visible region and a high optical bandgap (3.67 eV). Room-temperature photoluminescence (PL) spectra revealed a weak UV emission and a strong violet emission peaks for all films. However, the violet emission intensity being lower in ZnO: UV and ZnO: MF films due to a reduction in zinc interstitials (Zni) defects, The simultaneous UV and MF exposure did not reduce Zni defects, and the violet emission intensity was almost identical to that of the untreated film. These findings suggest that the ZnO: (UV+MF) film can be a promising candidate for the development of ultraviolet and violet lasers and light-emitting diodes.
