“…The absorbance peak for ZnO is seen at 374 nm, while the absorbance of Nb/st-integrated ZnO samples was not significantly different (only minor fluctuations (1–4 nm) in absorption spectra of doped ZnO were observed). Additionally, codoped ZnO samples showed a blue shift when compared to pure ZnO QDs. ,, The quantum confinement effect (QCE) is said to cause a blue shift in the band gap when the size of the particle is decreased in the metal oxide process. However, QCE is not the only reason; doping can disrupt symmetry and result in defects of lattice centers, which changes band architecture and cause major variations in optical characteristics .…”

Nb/starch-doped ZnO quantum dots (QDs) were prepared by a coprecipitation route. A fixed quantity of starch (st) and different concentrations (2 and 4%) of niobium (Nb) were doped in a ZnO lattice. To gain a better understanding of synthesized nanostructures, a systematic study was carried out utilizing several characterization methods. The goal of this research was to undertake methylene blue (MB) dye degradation with a synthetic material and also study its antibacterial properties. The phase structure, morphology, functional groups, optical properties, and elemental compositions of synthesized samples were investigated. Our study showed that ZnO QDs enhanced photocatalytic activity (PCA), resulting in effective MB degradation, in addition to showing good antimicrobial activity against Gram-negative relative to Gram-positive bacteria. Molecular docking study findings were in good agreement with the observed in vitro bactericidal potential and suggested ZnO, st-ZnO, and Nb/st-ZnO as possible inhibitors against dihydrofolate reductase (DHFRE. coli) and DNA gyraseE. coli.

“…Transparent conductive oxide (TCO) thin films have a significant research value and are widely used in many applications such as solar cells, display devices, photoelectronic devices, and touchscreens [1][2][3][4]. Metal oxides commonly used in TCO thin film systems include cadmium oxide (CdO), zinc oxide (ZnO), tin oxide (SnO 2 ), and indium oxide (In 2 O 3 ) [5][6][7][8]. The demand for TCO thin films has increased over the last few years with the rapid development of various devices.…”

The detection and real-time monitoring of temperature parameters are important, and indium oxide-based thin film thermocouples can be integrated on the surface of heaters because they operate normally under harsh conditions and provide accurate online temperature monitoring. The higher stability and appropriate optical and electrical properties of In2O3 make it very suitable as an electrode material for thermocouple sensors. This work demonstrates that copper doping can alter the optical and electrical properties of In2O3 films and regulate the output performance of thermocouples. Copper-doped In2O3 thin films were prepared using the magnetron co-sputtering method. The doping concentration of Cu was controlled using direct current (DC) power. An In2O3/Pt thermocouple sensor was prepared, and the optoelectronic and thermocouple properties were adjusted by changing the copper doping content. The thickness valve of the thin film sample was 300 nm. The results of the X-ray diffraction suggested that the structure of the doped In2O3 thin films was cubic. The results of the energy-dispersive X-ray analysis revealed that Cu was doped into the In2O3 thin films. All deposited films were n-type semiconductor materials according to Hall effect testing. The 4.09 at% Cu-doped thin films possessed the highest resistivity (30.2 × 10−3 Ω·cm), a larger carrier concentration (3.72 × 1020 cm−3), and the lowest carrier mobility (0.56 cm2V−1s−1). The optical band gap decreased from 3.76 to 2.71 eV with an increase in the doping concentration, and the transmittance of the film significantly reduced. When the DC power was increased, the variation range of Seebeck coefficient for the In2O3/Pt thermocouple was 152.1–170.5 μV/°C, and the range of thermal output value was 91.4–102.4 mV.
