Plasmon-induced near-infrared electrochromism based on transparent conducting nanoparticles: Approximate performance limits

Infrared Surface Plasmon Polaritons on Semiconductor, Semimetal and Conducting Polymer

Near-infrared photochemistry at interfaces based on upconverting nanoparticles.

Near-infrared (NIR) light is better suited than ultraviolet (UV) light for biomedical applications because it penetrates deeper into tissue and causes less photodamage to biological systems. The use of NIR light to control biointerfaces has attracted increasing interest. Here, we review NIR photoreactions at interfaces based on upconverting nanoparticles (UCNPs). UCNPs can convert NIR light to ...

Nanotechnological Enhancement of Infrared Detectors by Plasmon Resonance in Transparent Conductive Oxide Nanoparticles

We investigated the use of plasmonic nanotechnology to enhance the performance of semiconductor infrared detectors. An increase of quantum efficiency, responsivity and specific detectivity is obtained by applying transparent conductive oxide (TCO) nanoparticles onto the surface of a photodetector. To this purpose we considered uncooled mercury cadmium telluride (HgCdTe) photoconductive detector...

Enhanced near-infrared electrochromism in triphenylamine-based aramids bearing phenothiazine redox centers†

A series of organosoluble polyamides based on N-phenothiazinylphenyl redox units showing anodically electrochromic characteristics both in the near-infrared (NIR) and visible light regions were prepared from the phosphorylation polyamidation reactions of a newly synthesized diamine monomer, 4,40-diamino-40 0-N-phenothiazinyltriphenylamine, with various dicarboxylic acids. These polymers were re...

High-performance transparent conducting oxide nanowires.

We report the growth and characterization of single-crystalline Sn-doped In2O3 (ITO) and Mo-doped In2O3 (IMO) nanowires. Epitaxial growth of vertically aligned ITO nanowire arrays was achieved on ITO/yttria-stabilized zirconia (YSZ) substrates. Optical transmittance and electrical transport measurements show that these nanowires are high-performance transparent metallic conductors with transmit...
