The effect of Au/Ag ratios on surface composition and optical properties of co-sputtered alloy nanoparticles in Au–Ag:SiO2 thin films

Thin films of Ag–Au nanoparticles dispersed in TiO2: influence of composition and microstructure on the LSPR and SERS responses

“…A careful analysis of the XRD patterns also indicates the existence of single peaks, meaning that only one phase might be present in the films thereby suggesting the formation of crystalline domains of Ag-Au (possibly bimetallic alloy nanoparticles). This claim is also in agreement with similar studies where Ag-Au where deposited in SiO2[49].…”

Optical and photocatalytic properties of TiO2/Ag–SiO2 nanocomposite thin films

“…Moreover, the noble metals deposited SiO 2 thin films [23,24] and TiO 2 thin films [25][26][27][28] were prepared to improve the recycle property of the photocatalyst. To the best of our knowledge, metal deposited bis-oxide thin film as photocatalyst has hardly been reported so far.…”

Microstructure and optical absorption properties of Au-dispersed CoO thin films

“…In the past decades, the nonlinear optical properties of metal nanoparticles embedded in various dielectric matrices such as SiO 2 [5,6], Al 2 O 3 [7], TiO 2 [8], NiO [9] and ZnO [10] were much investigated which is due to a strong surface plasmon resonance (SPR) of metal nanoparticles in the visible range. The SPR frequency, a significant characteristic parameter of the nonlinear optical properties, depends on the content, size, and shape of the metal particles, as well as the dielectric properties of metal particles and the surrounding matrix material [11].…”
