The dibenzoterrylene-C60 composite structure as a possible new single-photon source - growth and optical analysis

A sample fabrication approach based on organic molecular beam deposition creating a new molecule-based emitter structure and its optical analysis is presented. The polycyclic aromatic hydrocarbon dibenzoterrylene (DBT, C38H20) was deposited between layers of C60-fullerenes, which serve as a protecti...

Description
Summary:A sample fabrication approach based on organic molecular beam deposition creating a new molecule-based emitter structure and its optical analysis is presented. The polycyclic aromatic hydrocarbon dibenzoterrylene (DBT, C38H20) was deposited between layers of C60-fullerenes, which serve as a protective matrix. It was found that this structure maintains the DBT’s optical properties [1, 2], but a potentially quenching impact cannot be excluded. Raman spectra of the composite were collected proving the molecules’ preserved integrity after being evaporated at high temperatures. Finally, the results of confocal laser scanning microscopy show fluorescent molecular clusters.
