Laser-induced fluorescence of coumarin derivatives in aqueous solution: Photochemical aspects for single molecule detection
The efficiency of detecting a single fluorescent coumarin dye molecule in aqueous solution by one-photon excitation (OPE) at 350 nm as well as by coherent two-photon excitation (TPE) at 700 nm is studied. The photostability, which is crucial for single molecule detection (SMD), is determined at a lo...
