Time-resolved pl spectrum
Several new fullerene–heptamethine conjugates, which absorb as far as into the infrared spectrum as 800 nm, have been synthesized and fully characterized by physicochemical means. In terms of optical and electrochemical characteristics, appreciable electronic coupling between both electroactive species is deduced. The latter also reflect the … WebTime-resolved fluorescence • Problems of conventional fluorescence – Scattering – Autofluorescence • Spectral vs. temporal resolution – Limit >10 nm, 250 nm – 900 nm – Limit > 1 ns, 1 ns – 2,000,000 ns
