"using quantum systems... assemble molecular emitters into plasmonic picocavities which was resonant in both the MIR and visible ranges... molecular vibrational states and electronic states were able to interact, resulting in efficient transduction MIR light into enhanced visible luminescence... trap light in single-atom defects on metallic facets, extreme light confinement volume below 1 nm3... molecule level spectroscopy: real-time gas sensing, medical diagnostics, astronomical surveys and quantum communication"
