摘要：

An organic dye was doped into the naphtalimide (NA) emission layers of some organic thin-film electroluminescent (EL) diodes to evaluate those layers' EL emission intensity distribution and to understand their general emission properties. After a certain point, the nearer the doped layer was to the cathode, the weaker was its EL emission intensity; a steep drop-off began at approximately 25 nm. This phenomenon may result from exciton dissociation, due to the presence of a schottky barrier, at the emission layer/cathode interface.
