The spectroscopic investigation of poly(methyl methacrylate) (PMMA) co-doped with organic dyes (Fluorescein and Rhodamine B) is presented. The pair of dyes have been chosen for energy transfer mechanism investigation in PMMA host. The theoretical calculations of energy transfer based on obtained spectra measurements showed that non-radiative process occurs during excitation of specimens. The results of measurements and calculations of Fluorescence Resonant Energy Transfer (FRET) efficiency for excitations at 405 nm and 460 nm wavelength are determined. Investigated influence of excitation showed possibility of luminescence spectra modification. The tunable emission was obtained for different excitation wavelength and dyes concentration in PMMA..
