The influence of annealing treatments on the properties of Ag:TiO2 nanocomposite films prepared by magnetron sputtering

Alloyed nanoparticle-embedded alumina nanocermet film: A new attempt to improve the thermotolerance

“…However, the intensity of the peak at 38.1 • begins to decrease monotonically with extending the annealing time. Only one weak peak of (1 1 1) plane can be observed after annealing at 500 • C for 62 h. The time evolution of diffraction peak suggests that the volume fraction of Ag is gradually reduced, which in turn is stemmed from the outwards diffusion and even evaporation of the Ag elements [12,31,32]. The loss of Ag would aggravate the optical degradation of the Ag-Al 2 O 3 films during the long-time annealing, as shown in Fig.…”

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

“…Important to notice is the sample annealed at 700 ºC, where both anatase and rutile structures coexist. It is also worth mentioning that the peaks The delay in the crystallization of anatase in Ag:TiO 2 films has been already reported in other works [27] [31] and it is attributed to the increase of the activation barrier for crystallization by the Ag atoms, which are assumed to be fine distributed throughout the amorphous matrix [30]. Therefore, the nucleation of silver to form clusters during thermal annealing slows down the re-arrangement of Ti-O bonds, preventing its crystallization.…”

Evolution of the functional properties of titanium–silver thin films for biomedical applications: Influence of in-vacuum annealing

“…1) suggest the Ag diffusion to interstitials or even to lattice sites substituting the Ti atoms in the hcp-Ti structure [3,9,10,23,40,41], which could also affect the stress states of the films (not measured within the frame of this work). In this case, Ag seems to ay a f '' y ag'' h b g h g a c a g [24] and thus explaining the decrease in Ti grain size.…”
