Alloy formation and composition partitioning of plasmonic-magnetic Au−Fe nanoparticles embedded in sol-gel SiO2 films

Structural evolution under physical and chemical stimuli of metastable Au–Fe nanoalloys obtained by laser ablation in liquid

“…This contraction is due to the presence of Fe atoms as substitutional impurities in the Au lattice. 34,55 Furthermore, there is an evident background of non-crystalline material, which can be estimated to be 72 wt% (Fig. 4B).…”

Optical fiber sensor based on magneto-plasmonic features of Ag-Co nanostructure for ppm ammonium detection in aqueous solutions

“…To accomplish this desire, the combination of the materials having appropriate plasmonic properties and magneto-optical features can be a practical way. To obtain the greatest magneto-plasmonic system, there are several approaches such as noble metal/ferromagnetic metal nanocomposite thin films, noble metal/ferromagnetic metal multilayer structures, and noble metal/ferromagnetic dielectric structures [9][10][11][12][13]. Therefore, in this paper, we establish a magneto-plasmonic nanocomposite sensor system through the deposition of noble metal Ag/ferromagnetic metal Co in thin-film configuration on uncladded glass optical fiber.…”
