In an article recently published in Physical Review Applied, we study the influence of resonant optical nanoantennas made of silicon on the spontaneous emission properties of fluorescent molecules. This collaborative study highlights how dielectric resonators can either enhance or inhibit spontaneous emission ; and can also allow increased photon collection efficiencies in an optical microscope.
In a recent ACS Nano article, we describe the large-scale fabrication of colloidal single-photon emitters with lifetimes down to a few picoseconds and quantum yields that can reach 70 %. These emitters are obtained by introducing a single fluorescent molecule on the 10 nm-long DNA double-strand that links two gold nanoparticles. This study was performed in collaboration with Institut Fresnel in Marseille.
In a collaborative study with Institut Fresnel in Marseille, recently published in ACS Photonics, we discuss the non-radiative energy transfer between two fluorescent molecules positioned in the center of a gold nanoparticle dimer. Our results highlight the competition between raidative and non-radiative decay channels in a complex nanoscale photonic environment.
