Nano Lett 10:891-5. 2010..The combined effect of plasmonic field enhancement and high quality factor (Q approximately 900) opens new routes for the control of light-matter interaction at the nanoscale...
- Plasmon-enhanced upconversion in single NaYF4:Yb3+/Er3+ codoped nanocrystalsStefan Schietinger
Nano Optics, Institute of Physics, Humboldt Universitaet zu Berlin, Hausvogteiplatz 5 7, Berlin, Germany
Nano Lett 10:134-8. 2010..8 is reached. A comparison of time-resolved measurements on the bare nanocrystal and the coupled nanocrystal-gold sphere systems unveil that faster excitation as well as faster emission occurs in the nanocrystals...
- In situ observation of plasmon tuning in a single gold nanoparticle during controlled meltingAlexander Kuhlicke
AG Nanooptik, Institut fur Physik, Humboldt Universitat zu Berlin, Newtonstr 15, D 12489 Berlin, Germany
Nano Lett 13:2041-6. 2013..The melting process can be controlled allowing the formation of different particle heights and plasmon resonance shifts. In situ tuning of the plasmon resonance of individual particles is possible with this reversible melting process...
