Abstract :
We present a detailed investigation of energy transfer of optical excitations in a molecularly doped conjugated polymer. We have incorporated dye molecules into a polymer blend system consisting of poly (phenylphenylene vinylene) (PPPV) and polycarbonate. Using time-resolved luminescence spectroscopy we observe efficient picosecond energy transfer from the PPPV chromophores to the dye 4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran (DCM) molecules. Our results are interpreted in terms of Fِrster-type energy transfer.
