In this work we will present preliminary results on the development of a novel hybrid solid-state quantum emitter based on single dye molecules intercalated between two monolayers of transition metal dichalcogenides. The latter would provide almost perfect surface passivation and dye protection against photobleaching agents, as e.g. oxygen. Low spectral diffusion and an accordingly narrow and Fourier-limited emission linewidth at cryogenic temperatures of single molecules are expected and are investigated by optical means with a custom-built fluorescence confocal microscope. Being nanometre thin, this novel quantum emitter would be naturally prone to be efficiently couple to the evanescent field supported by nanophotonic devices, such as tapered optical fibers and on-chip high-Q microresonators. Strong light-matter interaction would be ensured as the emitter can be placed directly onto the surface of the nanostructure while causing only minimal scattering losses, hence representing a promising alternative to the currently available solid-state quantum emitters in sub-micrometric size crystals.
