Fluorescence behaviour of highly concentrated rhodamine 6G solutions [PDF]

Journal of Luminescence, 1987
The fluorescence quantum distributions E(X) and fluorescence quantum efficiencies qF of rhodamine 6G in methanol and in water are measured for various concentrations up to the solubility limit. The fluorescence spectra are separated in monomer and dimer (ground-state dimer and closely spaced pair) contributions.
