摘要

Molecular fluorescence from the surface of ZnTBP porphyrin (ZnTBPP) molecular layers on Cu(100) is induced with nanoprobe excitation in the tunnelling regime. The observed well-defined molecular fluorescence is a perfect match with the standard photoluminescence data of ZnTBPP molecules. The decoupling of the electronic state of the top layer ZnTBPP is controlled by the thickness of the molecular layers. The excitation mechanism of molecular luminescence may be attributed to the hot electron injection into the molecules in proximity to the tip apex of a scanning tunnelling microscope. This approach features simplicity, bipolar operation and good reproducibility. The research provides a new way for the integration of molecular fluorescence with a nanoprobe and the development of a nanoscale molecular light source.
