A plasmonic detector and method for manufacturing a plasmonic detector. The plasmonic detector comprises two nanoscale metallic rods coupled to a bias voltage; a nanoscale cavity formed between adjacent ends of the two nanoscale metallic rods; and an absorption material disposed in the nanoscale cavity for converting an electromagnetic field to an electric current for outputting via the nanoscale metallic rods.

A device for Surface Enhanced Infrared Absorption (SEIRA) that includes at least one pair of metallic antennas deposited on a substrate, wherein the pair of metallic antennas are collinear. The length, width, and height of the metallic antenna determines an infrared absorption of the pair of metallic antennas. The device also includes a gap located between the pair of metallic antennas. A chemical moiety is disposed on at least a portion of the metallic antennas such that the infrared absorption of the chemical moiety is enhanced by the at least one pair of metallic antennas.

Embodiments of the invention provide a WIFI distribution network prompt control method and device, and a WIFI device, and relates to the technical field of wireless communication. According to the method and device, when a router is successfully accessed, a connection request is initiated to a server through the router, a WIFI icon of a display module is controlled to maintain a normally turn-on state when the WIFI device and the server are successfully connected, and the WIFI icon of the display module is controlled to flicker for a first preset time with a preset first frequency when the WIFI device and the server are unsuccessfully connected. The WIFI icon of the display module is controlled to indicate whether the WIFI device is successfully connected with the server in different modesso that users can determine whether the WIFI device is successfully connected with the server through observation of the display state of the display module, and whether the reason of the distribution network failure is specifically the WIFI device or the router is determined through observation of the flickering frequency and the flickering time of the WIFI icon.

A method for the formation of surface enhanced Raman scattering substrates. The method produces thin substrates that have a nanoparticle ink deposited thereon. The nanoparticle ink may be any suitable nanoparticle ink such as silver, gold or copper nanoparticle ink which includes stabilized nanoparticles. The substrates and nanoparticle ink undergo a first step of heating in order to remove liquid vehicle from the ink The substrates and nanoparticles then undergo a second step of heating for an amount of time sufficient to remove a substantial portion of the stabilizer and provide a fractal aggregate nanoparticle layer on the substrate having a certain resistivity or conductivity suitable for Raman scattering. This creates SERS substrates with enhanced amplification properties.

Surface-enhanced raman scattering substrates

A method for producing planar extended electrodes with nanoscale spacings that exhibit very large SERS signals, with each nanoscale gap having one well-defined hot spot. The resulting highly sensitive substrate has extended metal electrodes separated by a nanoscale gap. The electrodes act as optical antennas to enhance dramatically the local electromagnetic field for purposes of spectroscopy or nonlinear optics. SERS response is consistent with a very small number of molecules in the hotspot, showing blinking and wandering of Raman lines. Sensitivity is sufficiently high that SERS from physisorbed atmospheric contaminants may be detected after minutes of exposure to ambient conditions.
