Article Synopsis
- Researchers use laser spectroscopy at very low temperatures (2 K) to study single dibenzoterrylene (DBT) molecules in tiny anthracene crystals made through a special printing technique.
- They find that the light emitted by these single molecules has very sharp transitions, almost as clear as those seen in bulk materials, indicating high-quality optical properties.
- By taking super-resolution images and changing the polarization of the light, they can measure the size and orientation of the crystals, which is important for future applications involving precisely placed quantum emitters.
We measure the quantum efficiency (QE) of individual dibenzoterrylene (DBT) molecules embedded in -dichlorobenzene at cryogenic temperatures. To achieve this, we combine two distinct methods based on the maximal photon emission and on the power required to saturate the zero-phonon line to compensate for uncertainties in some key system parameters. We find that the outcomes of the two approaches are in good agreement for reasonable values of the parameters involved, reporting a large fraction of molecules with QE values above 50%, with some exceeding 70%.
