Energy up-conversion (UC) luminescence provides higher energy of photons than incident light or electron. Since the use of UC is highly promising to improve efficiency of energy conversion devices, the UC luminescence has been actively studied. However, the detailed mechanism of UC luminescence has not been elucidated at a single-molecule level mainly due to the difficulty for measuring UC luminescence with ultimate spatial resolution.
In this study, we achieved to measure UC luminescence from a single phthalocyanine molecule, which is excited by tunneling current using an scanning tunneling microscope combined with photo-detection system. By measuring UC luminescence and electron conduction property, the mechanism of UC luminescence was elucidated at a single molecule level.
