Optical and structural properties of radiolytically in situ synthesized silver nanoparticles stabilized by chitosan/poly(vinyl alcohol) blends
(Radiation Physics and Chemistry, 2014)
In this study, the potential of chitosan/poly(vinyl alcohol) (CS/PVA) blends as capping agent for stabilization of Ag-nanoparticles (Ag NPs) during their in situ gamma irradiation induced synthesis was investigated. The ...
Photoluminescence of europium(III)-doped (YxSc1-x)(2)O-3 nanoparticles: Linear relationship between structural and emission properties
(Ceramics International, 2016)
Europium (III)-doped (YxSc1-x)(2)O-3 nanocrystalline powders of different compositions (x=0, 0.25, 0.5, 0.75 and 1) are synthesized using a polymer complex solution method. Comparative structural and optical characterization ...
WO3/TiO2 composite coatings: Structural, optical and photocatalytic properties
(Materials Research Bulletin, 2016)
WO3/TiO2 and TiO2 coatings were prepared on titania substrates using facile and cost-effective plasma electrolytic oxidation process. The coatings were characterized by X-ray diffraction, scanning electron microscopy, ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Ceramics International, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Structural and optical characteristics of silver/poly(N-vinyl-2-pyrrolidone) nanosystems synthesized by gamma-irradiation
(Radiation Physics and Chemistry, 2012)
Silver nanoparticles (AgNPs) were synthesized in situ by gamma-irradiation using poly(N-vinyl-2-pyrrolidone) (PVP) as a capping agent. The concentration, molecular weight and the structure (crosslinked and interpenetrated ...
Preparation of Y2O3:Eu3+ nanopowders via polymer complex solution method and luminescence properties of the sintered ceramics
(Ceramics International, 2011)
Herein we presented polymer complex solution method for production of well crystalline europium doped Y2O3 nanopowders. Polyethylene glycol (PEG) of five different molecular weights is used both as a fuel and as a nucleation ...
Multisite luminescence of rare earth doped TiO2 anatase nanoparticles
(Materials Chemistry and Physics, 2012)
Eu3+, Sm3+ and Tb3+ ions have been incorporated into anatase TiO2 nanocrystals via hydrolytic sol gel method. Pure anatase phase was confirmed with XRD and TEM measurements. Band gap energies change slightly with rare earth ...
Characterization of silver/polystyrene nanocomposites prepared by in situ bulk radical polymerization
(Materials Research Bulletin, 2014)
Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine ...
Changes of properties of cured and uncured disiloxane bisbenzocyclobutene thin films under irradiation
(Progress in Organic Coatings, 2013)
The effects induced by alpha-particles and laser beam irradiation in air atmosphere in uncured and cured bisbenzocyclobutene (BCB) 2 mu m thick films, spin-coated on glass/ITO surface have been investigated. alpha-Particle ...
Photocatalytic degradation of alprazolam in water suspension of brookite type TiO2 nanopowders prepared using hydrothermal route
(Materials Chemistry and Physics, 2015)
Two series of nanocrystalline brookite-type powders have been synthesized by using combined sal gel hydrothermal method with titanium tetrachloride (TiCI4) as a precursor and hydrothermal temperature and reaction time ...
