Enhancement of laser recording in gold/amorphous chalcogenide and gold/acrylate nanocomposite layers

Influence of gold nanoparticles on the photo-polymerization processes and structure in acrylate nanocomposites

“…After the UV curing homogeneous and transparent films of red color were obtained. Optical absorption band due to the plasmon resonance absorption of GNP was clearly observed at 530 nm in these films [5].…”

“…In our previous works [4,5] transmission electron microscopic (TEM) studies were performed on different monomers (UDMA, IDA) doped with SiO 2 NP and GNP. It was established that the agglomeration of GNP can be avoided by addition of SiO 2 NP to the composition.…”

“…Recently it was shown, that gold nanoparticles (GNP) influence the holographic recording in acrylatebased nanocomposites, resulting in increased diffraction efficiency of the fabricated gratings [4,5]. The influence of the plasmon fields of nanoparticles, for example gold or silver ones, on optical processes, luminescence in organics and other materials was also demonstrated and published in a number of papers [6,7].…”

Patterning photosensitive layers for optoelectronic applications

“…Gold nanoparticles (GNP) and nanocomposite structures with GNP are of special interest because of the presence of plasmon resonance in a visible, green-red spectral range or even at longer wavelengths, depending on the form and dimensions of the GNPs. We had shown that GNPs influence the structural transformations not only in chalcogenide glasses, called sometimes as "inorganic polymers", but also in acrylate-based organic materials [3,4]. Therefore in the present paper we present data on optical recording, based on formation of surface patternsholographic gratings in samples, based on these materials.…”

“…Their applications in optoelectronics are mostly connected with large-scale changes of optical characteristics, their modulation by a number of external influences (electrical, optical, thermal fields) parallel with possible changes of dimensions, structure of the given element (lens, diffractive element, waveguide). Therefore, in the last decade the development of light-sensitive chalcogenide glasses and polymers for photonic applications was directed not only to the creation of new compositions but also to the goal-oriented fabrication of layered nanocomposites like amorphous chalcogenideamorphous chalcogenide, or amorphous chalcogenidemetal [1,2], as well as nanocomposites with gold nanoparticles (GNP) [3,4]. Gold nanoparticles (GNP) and nanocomposite structures with GNP are of special interest because of the presence of plasmon resonance in a visible, green-red spectral range or even at longer wavelengths, depending on the form and dimensions of the GNPs.…”
