“…7) of the studied hybrid materials show the appearance of strong diffraction peak centered at 19°of 2h which is attributed to the PVA crystalline phase [18]. Two weak diffraction peaks at 2h equal to 38°and 42°are observed and they are attributed to the (1 1 1) and (2 0 0) Bragg reflections of the face-centerd cubic (fcc) structure of metallic silver, which confirms the formation of metallic silver nanoparticles [39].…”

“…In the case of composite materials, basically two approaches can be found, either in situ synthesis of metal nanostructures in the matrix using chemical, thermal or photoinduced reductions; or incorporation of nanoparticles colloidal dispersions during the matrix preparation. The matrix can typically be inorganic, [496][497][498][499] sol-gel based matrix [215,[500][501][502][503][504][505][506][507][508][509][510] or polymers. [511][512][513][514] Regarding the in situ growth, the main drawbacks are the limitations in terms of control of the shape of the particles, which are often spherical or wire-type structures and the homogeneity in size and dispersion.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…The organic-inorganic hybrid nanocomposites comprising of polymer, and nanoparticles were synthesized through sol-gel technique at ambient temperature. The inorganic phase was generated in situ by hydrolysis-condensation of tetraethoxysilane (TEOS) in different concentrations, under acid catalysis, in presence of the organic phase, polymer, dissolved in formic acid [24]. Penetration of nanofillers into polyvinyl chloride has been shown by SEM measurements in Figure 2.…”

Abstract--This paper aims to provide a view of a lively space charge accumulation in new polyvinyl chloride (PVC) nanocomposite thin films. Space charges in thin films of polyvinyl chloride nanocomposite insulation materials are done to distort the local electric fields and affect high-field conduction and breakdown phenomena, whatever, adding nanofillers to polyvinyl chloride changes their electrical ages. Thus, space charge characteristics have been investigated by pulsed electroacoustic (PEA) measurement system for thin thickness of polyvinyl chloride nanocomposite materials which filled with different separately nanoparticles like ZnO, TiO 2 , and Al 2 O 3 . This paper depicts that space charge accumulation in polyvinyl chloride nanocomposites differs with respect to type and concentration of nanoparticles.
