AB  - In this research was the study of the phenomenon of fluorescence energy transfer between two laser
dyes. One models have been prepared in this study, the acceptor dye (acridine orange) with the donor dye
(rhodamine B). The absorption spectra and the emission spectra of the acridine orange and rhodamine B dyes
were studied with different concentrations (1×10-3, 1×10-4, 1×10-5) mL in ethanol solvent. The results of the study
showed a significant increase in the intensity of the fluorescence spectra of the mixing samples compared to
the dyes individually for all the prepared samples. We note change all the linear optical properties (absorption
coefficient, refraction index, quantum yield, lifetime of the energy level of fluorescence) of (acceptor+donor )
samples prepared compared to what it was before mixing.
