This article presents the latest results of rhodamine B and fluorescein solutions emissions at different weight concentrations. The shift of emitted central peak wavelength is observed to change in weight concentrations of the active material in samples. By using only two active materials photoluminescence at desired wavelength form range 524nm – 660nm can be achieved. All samples were excited sequentially by a laser source and two blue light-emitting diodes without significant changes in the emitted spectra.
