摘要：

Electroluminescence is excited in poly(ethylene 2,6-naphthalate) films submitted to a d.c. field. Kinetic and spectral analysis of the light emitted after field removal, so-called delayed luminescence, is carried out in order to understand the phosphorescence enhancement observed in electroluminescence. It is shown that light emission can be interpreted in terms of tunnelling recombination of deeply trapped electrons to the luminescent centres formed by the ionized molecules. The phosphorescence enhancement is due to direct coupling between the trapping state and the triplet state of the molecule.
