摘要：

The investigation of the magnetic field effect (mfe) of the intensity of fluorescence excited in thin films of poly(2-phenyl-1,4-phenylene vinylene) (PPPV) leads to the conclusion that the delayed part (being only sensitive to an applied magnetic field) is due to geminate recombination of charge carriers. The temperature dependence of the magnetic field effect has permitted the estimate of the difference between the energy levels of the excited fluorescenting state and the geminate electron-hole pair. The fitting of the experimental curve yielded DELTAE = 0.05 eV.
