摘要

Excitation energy transfer between tris-(8-hydroxyquinoline) aluminum (Alq3) and a red dye 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)- 4H -pyran (DCM) has been investigated by means of in situ measurements of photoluminescence (PL) of bilayer Alq3 DCM films with various Alq3 thicknesses. It is found that exciton diffusion in Alq3 and Förster energy transfer from Alq3 to DCM are contributive to the PL spectra measured. A rate equation model based on these two processes is derived and used to fit experimental results. The Förster energy transfer radius obtained for the system is R0 =3.3±0.1 nm. Energy transfer in the blend system is also analyzed based on the model.
