    Molecules Adsorbed onto Hexagonal Boron Nitride

## Description

- description: Fluorescence spectra of single terrylene molecules adsorbed on hexagonal
    boron nitride (hBN) flakes were recorded at cryogenic temperatures. The pure electronic
    transitions of terrylene molecules are spread over a broad energy scale, from
    570 to 610 nm. Surprisingly, peaks in the vibrationally resolved fluorescence
    spectrum show intensity variations up to 20-fold between molecules. We find an
    extreme case where the Debye-Waller-Franck-Condon factor of the zero-phonon line
    exceeds 0.8. The vibronic intensity correlates both with the spectral position
    of the electronic transition and with the frequency of the longitudinal stretch
    mode, which varies between 243 and 257 cm-1 . By means of DFT calculations, we
    show that these observations can be explained by terrylene chemisorption on charge-
    donating defect sites. The electronic states of molecules at such chemisorption
    sites would be very attractive for the efficient emission of single photons with
    narrow lines and for the generation of indistinguishable photons.
