“…These procedures may include the vapor-solid or vapor-liquid-solid growth, chemical or physical vapor deposition, metal organic chemical vapor deposition, and the thermal oxidation of metals [21][22][23][24]. The vapor phase deposition method is mainly performed at elevated temperatures under the gas flow in a chamber [23,25]. Great efforts have been made for the fabrication of one dimensional (1D) and thin film metal oxide nanostructures using the chemical vapor deposition (CVD) method, which involves the formation of nanomaterials onto the substrate by the chemical reactions of vapor phase precursors [5,[26][27][28].…”

Metal oxide materials have been applied in different fields due to their excellent functional properties. Metal oxides nanostructuration, preparation with the various morphologies, and their coupling with other structures enhance the unique properties of the materials and open new perspectives for their application in the food industry. Chemical gas sensors that are based on semiconducting metal oxide materials can detect the presence of toxins and volatile organic compounds that are produced in food products due to their spoilage and hazardous processes that may take place during the food aging and transportation. Metal oxide nanomaterials can be used in food processing, packaging, and the preservation industry as well. Moreover, the metal oxide-based nanocomposite structures can provide many advantageous features to the final food packaging material, such as antimicrobial activity, enzyme immobilization, oxygen scavenging, mechanical strength, increasing the stability and the shelf life of food, and securing the food against humidity, temperature, and other physiological factors. In this paper, we review the most recent achievements on the synthesis of metal oxide-based nanostructures and their applications in food quality monitoring and active and intelligent packaging.

“…When this growth progresses towards the formation of the same type of crystal faces, they form a free surface. This mode of growth represents a choice of orientation and leads to competitive growth [21][22][23][24][25][26][27][28]. The preferred orientation for ZnO micro-scale rods is (002), along the c-axis.…”

“…Among the ZnO nanostructures, one dimensional nano-rods (1D) have been in the focus of current research in physics, chemistry, and material science due to their technological applications as well as their fundamental research importance. The growth of 1D structures such as nano-rods have been reported for ZnO doped with B, Al, Li, Mg, and In, for example, in [1,27]. The microscopic scenario is that Zn atoms in ZnO take their place in the crystal lattice.…”

Intrinsic and dandelion-like microflower nano-rod structures of boron-doped ZnO thin films were synthesized with an ecofriendly and cost-effective chemical bath deposition technique from an aqueous solution of zinc nitrate hexahdyrate [Zn(NO3)2.6H2O] as a precursor solution and boric acid as a doping solution. The boron concentrations were 0.1, 0.3, 0.5, 1.0, 3.0, 5.0, and 7.0 by volume. Scanning electron micrographs showed that doping with boron appears to hinder the vertical alignment of crystallites. Additionally, independent hexagonal nano-rod structures were observed to coalesce together to form dandelion-like structures on the film’s surface. The atomic ratio of the elements was determined via the X-ray photoemission spectrum technique. There were no substantial changes in the vibration structure of the film upon doping in terms of the Raman spectra. The optical band gap of ZnO (3.28 eV) decreased with B doping. The band gap of the ZnO:B film varied between 3.18 and 3.22 eV. The activation energy of the ZnO was calculated as 0.051 eV, whereas that of the ZnO:B film containing 1.0% B was calculated as 0.013 eV at low temperatures (273–348 K), versus 0.072 eV and 0.183 eV at high temperatures (348–523 K), respectively. Consequently, it can be interpreted that the 1% B-doped ZnO, which has the lowest activation energy at both low and high temperatures, may find some application areas such as in sensors for gases and in solar cells.

In this research contribution, the idea is created that Ln 3+ -doped nanosolid micelles have first been applied to enhance the photovoltaic properties of novel hybrid polymer solar cells (HPSCs). Among other publications in the literature, we have never found the same or similar work to be published previously. The new method of Ln 3+ -doped diblock copolymer (DBC) to develop nanosolid micelle luminescent materials is established. Very importantly the applicable technique to incorporate nanosolid micelles into PSCs by spin-coating on the surface of the indium tin oxide (ITO) layer is accomplished after comparing the different cooperation methods. This research contribution elucidates two novel HPSCs containing Ln 3+ nanosolid micelles formed by Ln 3+ -doped diblock copolymer (Ln 3+ -DBC) and organic conjugated ligands. The Ln 3+ -DBC luminescent nanosolid micelles (LNSMs) are formed via coordination between Ln 3+ ions and DBC, and are readily dispersed in a hydrophobic solvent. Nanosolid micelles can be incorporated into PSCs by spin-coating on the surface of the indium tin oxide (ITO) layer, to increase the absorption of sunlight. Critically, the presence of the LNSMs increases PSC absorption of light and increases the power conversion efficiency (PCE) of PTB7-Th/PC 71 BM-based devices from 8.68% to 9.61%, increased by 10.71%, which is mainly caused by the enhanced short-circuit current density (J sc ), increased by 12.69% . In addition, the incorporation of LNSMs improved the stability of devices by protecting the active materials' degradation from UV light.
