Article Description

The research is dealing with the absorption and fluorescence spectra for the hybrid of an Epoxy Resin doped with organic dye Rhodamine (R6G) of different concentrations (5*10, 5*10 1*10, 1*10, 5*10) Mol/ℓ at room temperature. The Quantum efficiency Q, the rate of fluorescence emission K (s), the non-radiative lifetime τ (s), fluorescence lifetime τ and the Stokes shift were calculated. Also the energy gap (Eg) for each dye concentration was evaluated. The results showed that the maximum quantum efficiency 62 % and maximum stokes shift 96 nm was obtained in dye concentration 5*10 and 1*10. The energy gap ranges between 1.066 eV to 1.128 eV depending proportionally on the dye concentrations.
