Synthesis and Characterization of Bifacial Porous Silicon Modified with Tri-Metal Nanocomposites
This research presents a novel approach to effectively modify the characteristics of bifacial porous silicon (B-PSi) layers using tri-metallic nanoparticles. The B-PSi was synthesized by double beam laser-induced etching (D-LIE) of an n-type silicon substrate using 533-nm wavelength lasers at 80-mW power. Tri-metallic nanoparticles with a core/shell configuration, composed of Au, Ag, and Pd, were then incorporated onto the B-PSi surface through a dipping process in a solution with a 1:1:1 volumetric ratio of HAuCl4, AgNO3, and PdCl2 at 2-mM concentration for 4 min. The structural, spectroscopic, and morphological properties of the bare B-PSi were significantly modified by the deposition of the tri-metallic nanoparticles. Notably, the bifacial faces of the porous silicon layer exhibited a high degree of symmetry in terms of grain sizes of the tri-metallic nanoparticles, surface morphology, photoluminescence emission, and chemical bonding, both before and after nanoparticle deposition. This simple yet novel approach demonstrates an effective method for tailoring the characteristics of bifacial porous silicon layers through the integration of tri-metallic nanostructures.
期刊介绍:
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
