Highly textured pure and Al doped ZnO thin films have been produced by pulsed laser deposition for optical gas sensor application. The influence of the processing parameters such as substrate temperature oxygen pressure applied during depositions, dopant concentration on structural, morphological, properties were investigated. All deposited are along (002) direction. stronger film crystallinity compared to presence dopants. grain size prepared from 2 wt% Al2O3 target is approximately same...
We present a fast and flexible method for the fabrication of Au nanocolumns. nanostructures were produced by pulsed laser deposition in air at atmospheric pressure. No impurities or compounds detected resulting samples. The nanoparticles nanoaggregates ablated plasma pressure led to formation chain-like on substrate. dependence surface morphology samples geometry used experimental set up was studied. Nanocolumns different size density varying angle between plume electrical, optical,...
A simple sensor element consisting of a side-polished single-mode fiber and planar metal oxide waveguide is described. The thin ZnO was produced on the polished surface by pulsed laser deposition at optimized processing parameters. measurement scheme for in situ control film thickness during process developed used. X-ray diffraction measurements scanning electron microscopy were used to characterize structure morphology waveguide, respectively. numerical evaluation sensitivity predicts...
In this work, we present the fabrication of thin films/nanostructures metals and metal oxides using picosecond laser ablation. Two sets experiments were performed: depositions carried out in vacuum air at atmospheric pressure. The subjects investigation noble Au Pt ZnO TiO2. We studied compared phase composition, microstructure, morphology, physicochemical state as-deposited samples' surfaces air. It was found that ablation performed led to films with embedded differently sized...
We have conducted a new comparison of gold nanoparticles functionalized by primary- and secondary amine with the same chain length. Our hypothesis suggests that adaptive steric conformation molecular branches makes marked additional contribution to well-established role ligand characterize importance this factor based on diOctadecylamine (diODA) Octadecylamine (ODA) passivated using high-resolution transmission electron microscopy (HR-TEM) selective area diffraction (SAED). The results...
