In this work, the effects of atmospheric plasma treatment on morphology, optical, and electrochemical properties of 10 ± 3nm spherical silver and gold nanoparticles (AgNPs and AuNPs) functionalized substrates were studied. The nanoparticles (NPs) were deposited on substrates by drop-casting, aerosol spray, and a low-temperature atmospheric plasma-assisted aerosol jet. The reduction in nanoparticle size was observed, which was explained by the redox reaction that occurs on the nanoparticle surface. This phenomenon was evident by the presence of AgO, Ag2O, and AuOx Raman peaks in the treated sample. The surface charge changed as a result of plasma treatment, …

FIU Electronic Theses and Dissertations
Plasmonics, the science of the excitation of surface plasmon polaritons (SPP) at the metal-dielectric interface under intense beam radiation, has been studied for its immense potential for developing numerous nanophotonic devices, optical circuits and lab-on-a-chip devices. The key feature, which makes the plasmonic structures promising is the ability to support strong resonances with different behaviors and tunable localized hotspots, excitable in a wide spectral range. Therefore, the fundamental understanding of light-matter interactions at subwavelength nanostructures and use of this understanding to tailor plasmonic nanostructures with the ability to sustain high-quality tunable resonant modes are essential toward the realization of highly …

FIU Electronic Theses and Dissertations
Semiconductor nanostructures have attracted considerable research interest due to their unique physical and chemical properties at nanoscale which open new frontiers for applications in electronics and sensing. Zinc oxide nanostructures with a wide range of applications, especially in optoelectronic devices and bio sensing, have been the focus of research over the past few decades. However ZnO nanostructures have failed to penetrate the market as they were expected to, a few years ago. The two main reasons widely recognized as bottleneck for ZnO nanostructures are (1) Synthesis technique which is fast, economical, and environmentally benign which would allow the growth on …
