- Self-Assembly of Au@Ag Nanorods Mediated by Gemini Surfactants for Highly Efficient SERS-Active Supercrystals
Sergio Gómez-Graña, Jorge Pérez-Juste, Ramón A. Alvarez-Puebla, Andrés Guerrero-Martínez and Luis M. Liz-Marzán

The fabrication of supercrystals of standing core–shell gold–silver nanorods stabilized by gemini surfactants provides SERS substrates with high optical activity, large homogenous sensing areas, and the potential to maximize the SERS signal with respect to their gold nanorod supercrystal counterparts.

Thermoreversible on–off recording using time-dependent, persistent phosphorescence is demonstrated in air at room temperature using an organic film composed of an aromatic guest, phenol derivative, and steroid host. Reversible aggregation of guest molecules controlled by thermal hysteresis triggers large reversible changes in their time-dependent room temperature phosphorescence.

Coaxial microcavities etched into the surface of a doped silicon substrate are shown to support localized surface plasmon resonances at terahertz frequencies. This provides a promising pathway for the development of terahertz devices with application in the areas of photonic integrated circuits, molecular sensing, and subwavelength imaging.
- Arrays of Arbitrarily Shaped Nanoparticles: Overlay-Errorless Direct Ion Write
Gediminas Gervinskas, Gediminas Seniutinas, Lorenzo Rosa and Saulius Juodkazis
Article first published online: 3 MAY 2013 | DOI: 10.1002/adom.201300027
A simple method for the inscription of identical 20–30 nm features into single nanoparticles and their arrays is developed. Arrays of nanoparticles with exactly same optical properties can be used in nano-trapping including self-induced back-action trapping, Raman sensing, and metamaterial engineering.
- Oxide Surface Plasmon Resonance for a New Sensing Platform in the Near-Infrared Range

Surface plasmon resonance (SPR) is excited on transparent oxide semiconductors “In2O3: Sn” in the near infrared range. Coupling between excitations of surface plasmons and molecular vibrations are demonstrated. The detection sensitivity of oxide-based SPR is close to that of gold-based SPR working in the visible range. These studies evidence the useful potential of oxide-based SPR in the NIR range for sensing applications.
