Sub-molecular fluorescence microscopy with STM — •Guillaume Schull — IPCMS - CNRS/Unistra - Strasbourg

The electric current traversing the junction of a scanning tunneling microscope (STM) may lead to a local emission of light that can be used to generate sub-molecularly resolved fluorescence maps of individual molecules [1]. Combined with spectral selection and time-correlated measurements, this hyper-resolved fluorescence microscopy approach allowed us to scrutinise the vibronic structure of individual molecules [2] to characterise the emission properties of charged species [3], to track the motion of hydrogen atoms within free-base phthalocyanine molecules [4] and to follow energy transfers between multi-molecular architectures [5].
