Abstract
Energy transfer of binary dye mixture (Rhodamine110, as donor, and Oxizine1and/or Nile blue as acceptors) doped in organically modified silicates (ORMOSILs) matrix has been studied. The energy transfer process from donor molecules to acceptor molecules in the final bulk samples has been observed spectrally. Some of energy transfer parameters have been determined as a function of acceptor concentration. Stern-Volmer relation of energy transfer has been proved and the dominant mechanism of the energy transfer of dye mixture doped in such matrices has been determined. The results show that the emission properties of acceptor molecules (Ox1 and Nb) can be enhanced using the dye mixing recipe in sol-gel matrices.
