^a“Dye” indicates the name of the dye dissolved in ethanol; λ_exc is the wavelength of excitation, in nanometers; λ_em is the wavelength of emission, in nanometers; τ is the lifetime, in nanoseconds; χ²r is the reduced χ²; and “lit. (ref)” are values for the lifetime, in nanoseconds (under different conditions), measured by other workers, and the citation to their work.
