TL;DR: In this article, two opposing tip-to-tip Au triangles have been fabricated with triangle lengths of 75 nm and gaps ranging from 16 to 488 nm, and the plasmon scattering resonance first blue shifts with increasing gap, and then red shifts as the particles become more and more uncoupled, while perpendicularly polarized excitation shows little dependence upon gap size.

TL;DR: In this article, the authors show that individual lanthanide-doped upconverting nanoparticles (UCNPs) with multiple Yb3+ and Er3+ dopants exhibit bright anti-Stokes visible upconverted luminescence with exceptional photostability when excited by a 980nm continuous wave laser.

TL;DR: Optically resonant metallic bowtie nanoantennas are utilized as fabrication tools for the first time, resulting in the production of polymer resist nanostructures <30 nm in diameter at record low incident multiphoton energy densities.

TL;DR: Strong fluctuations of selected Raman lines imply that a small number of p-mercaptoaniline molecules on a single bowtie show chemical enhancement >10(7), much larger than previously believed, likely due to charge transfer between the Au surface and the molecule.

TL;DR: In this article, a three-dimensional linear-tapering approach was proposed to focus 830 nm light into a 2 × 5 nm^2 area with ≤3 dB loss and an intensity enhancement of 3.0 × 10^4.
