We report on the two-photon excitation and subsequent plasmonic mode relaxation of coupled optical gold nanoantennas. Using pulsed laser excitation at a constant wavelength of 810 nm, we observe two-photon-induced plasmon emission spectra, find them

We experimentally determine the order of multiphoton induced luminescence of aluminum nanoantennas fabricated on a nonconductive substrate using electron-beam lithography to be 2.11 (±0.10). Furthermore, we optically characterize these nanostructure

We record two-photon luminescence (TPL) emission spectra for two-arm nanoantennas of width 20 nm, height 30 nm and variable arm length of 25 to 65 nm, with a 20 nm gap between the arms, fabricated on an indium tin oxide (ITO) covered glass substrate

Two-photon excitation induced photoluminescence (2PE-PL) microscopy of CdSe colloidal quantum dots at the single-entity level is demonstrated. We provide evidence for single nanoparticle microscopy in the two-photon excitation regime by varying the l

We perform two-photon excitation confocal experiments on coupled gold nanoantennas and observe time-integrated luminescence spectra that match plasmonic mode emission in the far-field. We show that the transversal particle plasmon mode can be excited

Single-molecule microscopy is a powerful tool for investigating various uptake mechanisms of cell-penetrating biomolecules. A particularly interesting class of potential transporter molecules are peptoids. Fluorescence labels for such experiments nee

We investigate gold nanorods that are excited non-resonantly using a femtosecond 800 nm pulsed laser beam. We find that they emit very localized white light – two-photon induced photoluminescence (PL) – spatially confined in the optical far-field

In this paper we present our approach for engineering gold dipole nanoantennas. Using electron-beam lithography we have been able to produce arrays of single gold antennas with dimensions from 70 to 300 nm total length with a highly reproducible nano
