Optical investigation of gold shell enhanced 25 nm diameter upconverted fluorescence emission

Nanotechnology, 27(13), 135201.

By: K. Green n, J. Wirth* & S. Lim*

author keywords: plasmonic; upconversion; gold shell; fluorescence; time-resolved; AFM; structure and optical correlation
TL;DR: It is demonstrated that fluorescence enhancement is based on the photonic properties of single, isolated particles and the rate of photon emission is not suppressed, as would be expected for a metallic cavity, but rather enhanced because the metal shell acts as an optical antenna, with differing efficiency at different wavelengths.

TL;DR: An experimental investigation of the magnitude of length and density fluctuations in DNA that has been stretched in nanofluidic channels finds that the experimental data can be described using a one-dimensional overdamped oscillator chain with nonzero equilibrium spring length and that a chain of discrete oscillators yields a better description than a continuous chain.
