A terahertz metamaterial perfect absorber is demonstrated with an optical modulation capability whereby terahertz absorption is controlled using an 800 nm pump beam. The proof of concept device shows several prominent properties at various absorption bands such as a large modulation depth, narrow and broad band absorption, and antagonistically modulated absorptions, constituting a multipurpose toolbox for different applications.

Highly fluorescent, photostable, conjugated polymer dots (CPDs) based on polydiphenylacetylene (PDPA) provide highly porous, coarsened nanoparticles with a fully relaxed intramolecular stacked structure in water. This distinctive structure achieves an extremely high fluorescence quantum efficiency by restraining collisional quenching and vibrational relaxation. The PDPA-based CPD is a very promising probe for long-term imaging and tracking in live cells.
- Widely Adjustable and Quasi-Reversible Electrochromic Device Based on Core–Shell Au–Ag Plasmonic Nanoparticles

Plasmonic effects in Au–Ag nanostructures are utilized to realize novel electrochromic devices. Quasi ordered Au–Ag core–shell nanoparticle array is realized by thermal evaporation of Au and electrochemical deposition of Ag into a SiO2 hole array assisted by anodic aluminium oxide membranes. The thickness of the Ag shell could be changed by alternating the electrochemical deposition time: as a result, the color of the device can be widely tuned through this electrical control.
- Optical and Structural Properties of Ultra-thin Gold Films
Anna Kossoy, Virginia Merk, Denis Simakov, Kristjan Leosson, Stéphane Kéna-Cohen and Stefan A. Maier
Article first published online: 25 SEP 2014 | DOI: 10.1002/adom.201400345
Optical transmission through continuous ultra-thin gold films deposited on glass is significantly affected by the non-abrupt transition between the gold layer and surrounding dielectrics. Void-free polycrystalline gold films as thin as approximately 5 nm are realized and a simple model is presented to account for the measured transmission, using the transfer-matrix method and the bulk dielectric function.
