Biological behaviour of thin films consisting of Au nanoparticles dispersed in a TiO2 dielectric matrix

Broadband Optical Absorption Caused by the Plasmonic Response of Coalesced Au Nanoparticles Embedded in a TiO2 Matrix

“…12 The small Au clusters that might exist in these as-deposited samples are too small to be resolved by XRD analysis, giving rise to amorphous-like patterns. 65 However, as soon as the films are subjected to thermal annealing, some XRD peaks started to appear, which were related with the crystallization of both Au NPs and TiO 2 matrix itself. These features were studied in a previous work by the authors, 12 where it was also evaluated how the change of Au concentration in the film affected the structural evolution of the annealed Au/TiO 2 films.…”

Significantly enhanced dielectric constant and energy storage properties in polyimide/reduced BaTiO3composite films with excellent thermal stability

“…6 However, their low dielectric constant (typically less than 10) impedes their practical applications in capacitors. 7 A promising strategy to enhance the dielectric constant of polymer materials is to incorporate ferroelectric materials with high dielectric constant (such as titanium dioxide (TiO 2 ), 8,9 BaTiO 3 , 10,11 Pb(Zr,Ti)O 3 , 12,13 BaSrTiO 3 , 14,15 K 0.5 Na 0.5 NbO 3 (ref. 16 and 17) and CaCu 3 Ti 4 O 12 (ref.…”

Thin films composed of Ag nanoclusters dispersed in TiO2: Influence of composition and thermal annealing on the microstructure and physical responses

“…In recent works it was studied the influence of gold concentration, dispersed in a TiO 2 matrix, and annealing temperature on the microstructural features and optical response of Au:TiO 2 thin films [12] [13] [14] [15]. The overall set of results showed that the growth of Au nanoparticles/clusters with different sizes and size distributions is highly dependent of the annealing temperature [14] and, on the other hand, the intermediate Au contents, i.e.…”
