Tuning single-molecule fluorescence by atomic-scale control of the local environment
Thiago G. L. Brito, Daniel Arribas, Sofia Canola +3
Molecules that absorb and emit light play a central role in microscopy, light-emitting devices and photosynthesis. Their fluorescence arises from well-defined radiative transitions…
Probing up-conversion electroluminescence of decoupled porphyrin molecules in a plasmonic nanocavity
Li-Qing Zheng, Fábio J. R. Costa, Abhishek Grewal +6
Molecular triplet states can produce significant phosphorescence and act as a relay state for luminescence, such as in up-conversion processes. While this property makes triplet em…
Gating single-molecule fluorescence with electrons
Katharina Kaiser, Michelangelo Romeo, Fabrice Scheurer +2
Tip-enhanced photoluminescence (TEPL) measurements are performed with sub-nanometer spatial resolution on individual molecules decoupled from a metallic substrate by a thin NaCl la…
Electrically driven cascaded photon-emission in a single molecule
Katharina Kaiser, Anna Rosławska, Michelangelo Romeo +3
Controlling electrically-stimulated quantum light sources (QLS) is key for developing integrated and low-scale quantum devices. The mechanisms leading to quantum emission are compl…
