Two kinds of cobalt thin films, labeled smooth and nanostructured according to their surface properties, were deposited on a glass substrate by varying the deposition conditions during magnetron sputtering. Complementary characterization techniques first used investigate internal microstructure these two which give evidence that film structure is dense close bulk while contains columnar-like structures few nanometers’ width surrounded an oxide layer. The shows linear magnetic behavior,...
The reflectance spectra of simple design GaN-based microcavities have been studied in the 5 K–300 K range. epitaxial structure consists silicon substrate and stack buffer layers as back mirror, a GaN active layer, 100 Å thick aluminium layer top mirror. Active thicknesses λ∕2, λ, or 3λ∕2 were investigated. samples with λ∕2 λ display an anticrossing behavior between cavity exciton modes, measured Rabi splittings 47 60 meV, respectively, both at room temperature.
Glasses embedded with silver nanoparticles (NPs) have attractive properties because their optical can be adjusted by varying the size, shape, and packing density of particles. Pulsed laser processing such composite glasses is a promising approach in glass engineering. In this study, growth NPs silver-exchanged soda-lime ultraviolet (UV) continuous wave (cw) irradiation demonstrated. Highly concentrated large diameters (roughly 100 nm) are spread over several micrometers near exposed area....
One-, two- or three-dimensional arrays of closely spaced silver nanoparticles may lead to new optical properties, due short long range coupling between their resonant surface plasmons, so that the spatially controlled growth provides an efficient way tune properties. Towards this way, we present here periodic pattern a glass with by continuous ultraviolet laser exposure. The formation 160 nm period is well described interference-based model which agrees experimental conclusions, mainly...
The synthesis of a soda‐lime glass doped by gold nanoparticles (Nps) is achieved using successively thermal poling and continuous wave (cw) ultraviolet (UV) laser exposure. formation Nps undoubtedly proved an absorption band characteristic their surface plasmon resonance (SPR), scanning electron microscopy, which reveals about 40 nm in diameter, located the very near region glass. Absorption spectroscopy also suggests bimetallic silver‐gold systems prepared exposure previously silver ions...
In this contribution, we report on the formation mechanism of silver nanoparticles in very near surface a ion-exchanged soda-lime silicate glass, by intense continuous wave laser exposure at 244 nm. We demonstrate that due to strong absorption, glass melts and Ag+ ions are efficiently reduced through redox reaction, which implies O2 molecules diffused from surrounding atmosphere into melt. Consequently, Ag atoms further precipitate nanoparticles, thanks high melt temperature. This is...

Zirconium oxide (ZrO<sub>2</sub>) is an intensively studied and used material due to its many remarkable physical chemical properties. The high performances of ZrO<sub>2</sub> allows use in applications such as coatings against corrosion, wear oxidation, optical applications, anti-counterfeiting, or medical dental prosthesis. There are methods synthesize among which we can mention reactive sputtering, vapor deposition, atomic layer deposition. These techniques well known thin film deposition...
