Spectroscopic and time-resolved study of novel molecular compounds for on-chip integrated quantum light sources

The ARTEMIS project aims to develop integrable quantum sources based on metal-organic compounds with transition metal and/or lanthanide ions. These materials exhibit tunable linear emission and nonlinear optical properties, enabling on-demand generation of single photons and entangled photon pairs or triplets. When integrated with plasmonic supernanostructured cavities, these molecular emitters achieve strong optical enhancement. Our group focuses on the quantum characterisation of the light emitted by these sources to explore their potential for new metrology and sensing applications in the quantum regime. Spectroscopic and time-resolved measurements on newly synthesized compounds Tb N(Bzlm)3 and Eu N(Bzlm)3 dissolved in DMSO at high concentration reveal narrow emission bands and relatively long decay times.
