Abstract
Regarded as an essential transition metal, gold holds significant research value in the academic realm. In this work, gold nanoparticles were prepared by a combination of magnetron sputtering and liquid-phase exfoliation. The nonlinear optical properties of gold nanoparticles had been systematically investigated by utilizing the open aperture Z-scan method with both nanosecond and picosecond laser sources, which were rarely involved in previous studies. Based on the saturation absorption properties of gold nanoparticles, we prepared a gold saturable absorber and successfully applied it in generating passively Q-switched pulses in Pr:YLF crystal laser and Nd:YAG crystal laser, respectively. And we also analyzed its optical limiting applications. Our systematic study confirms that gold nanoparticles are suitable as candidates for saturable absorbers and optical limiting materials.
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.
