Wavelength dependence of fluorescence spectra of liquid coumarin solutions


The excitation wavelength dependence of steady-state fluorescence spectra of low-viscosity dye solutions is reexamined. Measurements are made on some coumarins in methyl alcohol at room temperature. It is found that the fluorescence spectra depend on the excitation energy and their profile changes are due to the excitation wavelength dependence of… (More)
