Abstract
Cadmium oxide (CdO) thin film was grown on a glass substrate at room temperature using the Successive ionic layer adsorption and reaction (SILAR) method. The grown thin films were annealed at 3500C and 4000C for 30 min. Structural and optical properties of CdO thin films after annealing were examined. Analyzes were made with X-ray diffractometer (XRD) and Scanning electron microscope-Energy dispersive X-ray spectroscopy (SEM-EDAX) devices for structural properties, and UV–Vis devices for optical properties. The XRD peak intensities of CdO thin films exposed to annealing temperature increased and the crystal structure improved. The bandgap energy range decreased from 2.48 eV to 2.37 eV with the effect of annealing temperature.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
