Summary: Bismuth sulfide nanorods were prepared by thermolysis of a bismuth dithiocarbamate complex, and their microstructural and optical properties were studied at different temperatures. The interaction between oleylamine and dodecanethiol with the nanoparticles was found to be temperature-dependent. The nanorods exhibited different crystal sizes and lattice strains at different temperatures, with preferential growth direction change observed. The band-gap energies of the nanorods varied, and texture coefficients indicated preferential growth in some crystal directions.

Summary: The hydrothermal method was used to create dilute magnetic semiconductor nanoparticles of Zn1-xCoxO (x = 0, 0.01, 0.05, 0.09). The effect of cobalt doping on the microstructure, morphological and optical properties of Zn1-xCoxO was studied. The results showed that cobalt doping decreased the crystallinity of ZnO, but had little influence on the shape of the nanoparticles. Doped samples exhibited ferromagnetic behavior above room temperature, with the best performance observed at a Co content of 0.05. Doped ZnO nanoparticles showed improved dielectric, electrical conductivity, and magnetic properties compared to pure ZnO.

Summary: In this study, ZnO nanowires were prepared through an unexplored strategy of electrochemical anodization using an electrolyte medium based mainly on ethylene glycol and fluoride ions. The morphology and properties of the nanowires were found to be influenced by parameters such as temperature and voltage during anodization. The resulting ZnO exhibited potential characteristics for photoelectrochemical and photocatalytic applications, with a bandgap value estimated to be within [3.19-3.22] eV.

Summary: A simple negative temperature coefficient (NTC) thermistor material ZnO was synthesized by mechanical alloying and its structural and microstructural properties were investigated. Electrical properties were studied in the temperature range of 300-500 degrees C and frequency range of 100 Hz-1 MHz. The synthesized sample showed typical NTC behavior and the Steinhart-Hart equations were used to analyze its suitability for thermistor application.

Summary: This study investigated the impact of lead concentration (0-1 wt%) on the physical properties and photo-detection properties of zinc oxide thin films. All films were deposited using Aerosol Assisted Chemical Vapor Deposition (AACVD) techniques and characterized through various methods. X-ray diffraction analysis revealed the formation of single-phase hexagonal ZnO thin films with preferred orientation changes at a Pb concentration of 0.5wt%. The formation of nano-rods was observed in films prepared with 0.5 and 1wt% lead. The band gap values increased with increased Pb doping. The deposited films exhibited high sensitivity to UV light after long exposure.

Summary: Few-layered graphene was produced using substrate-free direct current arc discharge between graphite electrodes in a specially designed reactor chamber, with different carbon structures observed in different regions of the reactor. The study found that the properties of the graphene produced were greatly influenced by the temperature distribution and gradient around the arc plasma, affecting the deposition mechanism of carbon clusters in the reactor zones.

Summary: In this study, the co-precipitation approach was used to synthesize ZnO, Zn0.96Gd0.04O, and Zn0.96-xGd0.04CoxO nanotubes. The effects of gadolinium and cobalt doping on the microstructure, morphology, and optical characteristics of ZnO were investigated. It was found that gadolinium and cobalt doping did not affect the morphology of the nanotubes, but reduced the crystallinity of the samples. The doping also resulted in changes in the optical characteristics and electrical conductivity of the nanotubes.

Summary: Cobalt-doped ZnO thin films synthesized using chemical bath deposition show excellent UV photosensing properties, with nanowire morphology and hexagonal wurtzite crystal structure. Due to the replacement of Co2+ ions, an increase in crystallite size and decrease in bandgap was observed, leading to high photoabsorption capability, with the highest responsivity reaching 0.918 AW(-1).

Summary: In this work, Sr doped ZnO nano-needles were synthesized and characterized. The study showed that the crystallite size increased with the Sr content up to 5% and then decreased. Sr doping also caused a variation in the bandgap. The FTIR spectra confirmed the substitution of Sr in ZnO. PL spectra confirmed the formation of ZnO nanoparticles. The magnetization behavior confirmed the weak ferromagnetism in Sr doped ZnO nanoparticles. Cyclic voltammetry study suggested that Sr doped ZnO nanoflakes could be a promising electrode material for supercapacitor development.

Summary: This study successfully prepared low-temperature Sn-doped zinc oxide (TZO) thin films as electron transporting layers for perovskite solar cells, showing improved electrical properties with increasing annealing temperature. Element composition analysis revealed that a temperature as low as 140 degrees Celsius was sufficient for converting precursor gel film into TZO film. The perovskite solar cell utilizing low-temperature TZO thin film demonstrated higher power conversion efficiency compared to high-temperature ETLs.
