Preparation and characterisation of Ag incorporated Al₂O₃ nanocomposite films obtained by sol‐gel method

Abstract

Sol-gel route has been applied for a deposition of the thin films of aluminum oxide and Ag embedded in Al 2 O 3 films. The films are spin-coated on Si and quartz substrates with the film thickness of 120 nm. XRD analysis has been used for the determination of the film structure. FTIR spectroscopy is applied for studying vibrational properties of the obtained coatings. Optical characterization is done by UV-VIS spectroscopy. The formation of Ag nanoparticles has been confirmed by XRD and optical data. The sol-gel process is found to be useful technology for incorporation of Ag nanoparticles in the metal oxide matrices.

Synthesis and Characterization of Silver(I) Pyrazolylmethylpyridine Complexes and Their Implementation as Metallic Silver Thin Film Precursors

“…The excellent characteristics of metallic silver coatings, such as a great thermal and oxidative stability, high chemical resistance, high melting point, softness, plasticity, and high electrical conductivity compared to polymeric coatings or other carbonaceous materials, make them excellent candidates for technological applications that include bactericidal coatings, coatings for superconducting materials, optical filters, electrodes for dielectric layers, solid lubricants, and contacts in microelectronic circuitry . Silver films have been deposited by many techniques that can be divided into nonvapor phase (electrodeposition, sol–gel, photochemical deposition) and vapor phase (sputtering, , pulsed laser deposition, electron-beam evaporation, chemical vapor deposition ,, ) techniques. The choice of the deposition technique is strictly related to the chemical and physical properties of the silver precursor and the nature of the substrate.…”

Nanocomposite with high adsorption activity developed using stabilized silver modified alumina and TiO2-NPs incorporated into β-cyclodextrin-graphene oxide

“…This observation could be due to the crystalline phase of Ag species on the Ag/Al 2 O 3 [ 18 , 23 ]. The formation of Ag nanoparticles dispersed in thin Al 2 O 3 films was confirmed by these results [ 24 , 25 ]. The XRD data yielded peaks that also confirmed the presence of α-Al 2 O 3 , as in 2 theta angles of 35.1° corresponding to (104) [ 26 ].…”

Microstructure and 355 nm Laser-Induced Damage Characteristics of Al<sub>2</sub>O<sub>3</sub> Films Irradiated with Oxygen Plasma under Different Energy

“…In recent years, considerable attention has been given to Al 2 O 3 thin films. Many techniques can be used to prepare Al 2 O 3 films, such as reactive magnetron sputtering [5], molecular beam epitaxy [6], sol-gel [7], ion beam sputtering [8], chemical vapor deposition [9], atomic layer deposition [10], electron beam thermal evaporation [11], and so on. Among these techniques, electron beam evaporation is one of the most common methods for optical thin film deposition.…”
