  • In-plane plasmonic antenna arrays with surface nanogaps for giant fluorescence enhancement 

    Flauraud, Valentin; Regmi, Raju; Winkler, Pamina Martina; Alexander, Duncan T. L.; Rigneault, Herve; Hulst, Niek F. van; Garcia-Parajo, Maria F.; Wenger, Jerome; Brugger, Juergen (ACS, 2017-02-10)
    Article
    Open Access
    Optical nanoantennas have a great potential for enhancing light-matter interactions at the nanometer scale, yet fabrication accuracy and lack of scalability currently limit ultimate antenna performance and applications. ...
  • Isolating strong nanoantenna-molecule interactions by ensemble-level single-molecule detection 

    Saemisch, Lisa; Liebel, Matz; Hulst, Niek F. van (Royal Society of Chemistry, 2020-01-20)
    Article
    Restricted access - publisher's policy
    Traditionally, the nanoscale interaction between single photon emitters and plasmonic nanostructures is studied by relying on deterministic, near-perfect, nanoscale-control, either top-down or bottom-up. However, these ...
  • Multicolour single molecule emission and excitation spectroscopy reveals extensive spectral shifts 

    Piatkowski, Lukasz; Gellings, Esther; Hulst, Niek F. van (The Royal Society of Chemistry, 2015-07-16)
    Article
    Open Access
    We explore the distribution and shape of single molecule spectra at room temperature, when embedded in a polymer host. Multicolour excitation and emission spectroscopy is implemented to capture the full inhomogeneous ...
  • Nanoantenna enhanced emission of light-harvesting complex 2: the role of resonance, polarization, and radiative and non-radiative rates 

    Wientjes, Emilie; Renger, Jan; Curto, Alberto; Cogdell, Richard; Hulst, Niek F. van (Royal Society of Chemistry, 2014-10-03)
    Article
    Open Access
    Nanoantennae show potential for photosynthesis research for two reasons; first by spatially confining light for experiments which require high spatial resolution, and second by enhancing the photon emission of single ...
  • Nanoplasmonics: Concluding remarks 

    Hulst, Niek F. van (Royal Society of Chemistry, 2015-04-30)
    Article
    Open Access
    Faraday Discussions have a splendid reputation in stimulating scientic debates along the traditions set by Michael Faraday himself. The Faraday Discussion 178 on nanoplasmonics has been particularly appropriate. ...
  • Nanoscale Imaging and Control of hexagonal BoronNitride Single Photon Emitters by a Resonant Nano-antenna 

    Palombo Blascetta, Nicola; Liebel, Matz; Lu, Xiaobo; Taniguchi, Takashi; Watanabe, Kenji; Efetov, Dmitri K.; Hulst, Niek F. van (American Chemical Society, 2020-02-13)
    Article
    Restricted access - publisher's policy
    Defect centers in two-dimensional hexagonal boron nitride (hBN) are drawing attention as single photon emitters with high photo-stability at room temperature. With their ultra-high photon-stability, hBN single photon ...
  • Plasmonic Nanocavity Coupling 

    Hugall, James T.; Singh, Anshuman; Hulst, Niek F. van (ACS, 2018-01-08)
    Article
    Open Access
    The large losses of plasmonic nanocavities, orders of magnitude beyond those of photonic dielectric cavities, places them, perhaps surprisingly, as exceptional enhancers of single emitter light‐matter interactions. The ...
  • Propagation and localization of quantum dot emission along a gap-plasmonic transmission line 

    Castro-Lopez, M.; Manjavacas, A.; García de Abajo, Francisco Javier; Hulst, Niek F. van (OSA, 2015-11-02)
    Article
    Open Access
    Plasmonic transmission lines have great potential to serve as direct interconnects between nanoscale light spots. The guiding of gap plasmons in the slot between adjacent nanowire pairs provides improved propagation of ...
  • Resonant plasmonic nanoparticles for multicolor second harmonic imaging 

    Accanto, Nicolò; Piatkowski, Lukasz; Hancu, Ion M.; Renger, Jan; Hulst, Niek F. van (AIP, 2016-02-26)
    Article
    Open Access
    Nanoparticles capable of efficiently generating nonlinear optical signals, like second harmonic generation, are attracting a lot of attention as potential background-free and stable nano-probes for biological imaging. ...
  • Room Temperature Excitation-Emission Spectra of Single LH2 Complexes Show Remarkably Little Variation 

    Gellings, Esther; Cogdell, Richard J; Hulst, Niek F. van (ACS, 2020-03-06)
    Article
    Restricted access - publisher's policy
    Excitation spectroscopy gives direct insight in excited state manifold, energy transfer, transient intermediates, vibrations, etc. Unfortunately, excitation spectroscopy of single molecules at ambient conditions has ...
