Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

Herein flexible nanocomposite films composed of polyvinyl alcohol (PVA), polyaniline (PANI), and silver (Ag) are synthesized using solution cast technique for optoelectronics applications. The X-ray diffraction (XRD), transmission electron microscope (TEM), and UV absorbance have confirmed the successful synthesis of the nanocomposite films with uniform silver nanoparticles (AgNPs) embedded in the PVA/PANI blend. The optical bandgap of PVA/PANI blends and PVA/PANI/Ag nanocomposites is determined by ultraviolet (UV) absorbance, which shows a decrease compared with a pristine PVA film. Meanwhile, Urbach energy, absorption edge (Ed), the number of carbon clusters (N) were estimated. Furthermore, the influence of PANI and AgNPs on the reflection, refractive index, extinction coefficient, real and imaginary dielectric constant, and the optical conductivity is discussed. The results clear that the optical properties of PVA polymer modify by adding PANI and AgNPs. Based on that, the fabricated PVA/PANI/Ag nanocomposites films can be used in optoelectronic devices.
