“…332,333 In general, it would be very difficult or impossible to use other methods to fabricate the patterned arrays of metal strips, gratings, and holes essential to plasmonic waveguides and lenses. 384,385 However, in comparison to assembly, lithography is not as good at producing gaps controlled below 10 nm. Lithography also can only produce planer, thin-film architectures.…”

“…The associated thermal gradients are responsible for distributing silver into the shape of this buried grating since they promote not only the NP growth but are also a driving force for the NP motion and organization as reported in different experiments. 16,17,46 It is worth stressing that the formation of the buried NP grating is not initiated by the LIPSS formation process but by the higher temperature. The surface and guided modes propagate in perpendicular directions and Ag NPs initially grown in the LIPSS grooves cannot efficiently couple light into the guided mode.…”

Controlling plasmonic systems with nanometre resolution in transparent films and their colors over large non-planar areas is a key issue for spreading their use in various industrial fields. Using light to direct self-organization mechanisms provides high-speed and flexible processes to meet this challenge. Here, we describe a route for the laser-induced self-organization of metallic nanostructures in 3D. Going beyond the production of planar nanopatterns, we demonstrate that ultrafast laser-induced excitation combined with non-linear feedback mechanisms in a nanocomposite thin film can lead to 3D self-organized nanostructured films. The process, which can be extended to complex layered composite systems, produces highly uniform large-area nanopatterns. We show that 3D self-organization originates from the simultaneous excitation of independent optical modes at different depths in the film and is activated by the plasmon-induced charge separation and thermally-induced NP growth mechanisms. This laser color marking technique enables multiplexed optical image encoding and the generated nanostructured Ag NPs:TiO 2 films offer great promise for applications in solar energy harvesting, photocatalysis or photochromic devices.

Electrodeposition is used for the preparation of nanoparticles and nanostructures that allow, in principle, surface plasmon excitation. The (photo)electrodeposition process of Rh and Au nanoparticles as well as of heterodimeric enzymes onto silicon surfaces is investigated and the resulting structures are discussed with regard to applications in photoelectroctalysis and biosensing. Electrodeposition of Rh onto H-terminated p-Si surfaces generates nanostructures of the metal nanoparticles with simultaneous oxidation of the substrate thus forming nano-dimensioned metal-oxide-semiconductor (MOS)-type contacts. The excess minority carrier harvesting in these nanoemitter structures, where semispherical space charge layers underneath the metal exist are discussed based on spectral sensitivity and capacitance measurements The deposition of Au nanoparticles by a combined chemical-electrochemical method on Si is presented as an example for sensing actuators where the resonance frequency is changed by adsorption. Similarly, site-selective deposition of the enzyme reverse transcriptase onto nanostructured (step-bunched) silicon serves as precursor experiment for biosensing in a Kretschmann-type ATR configuration. Future applications based on plasmonically active structures are outlined.
