摘要：

The electrical and emission properties of poly (p-phenylene vinylene)-based light-emitting devices with different thicknesses of the emitting layer, and especially the influence of the ambient atmosphere, were examined. In vacuum anomalous current-voltage characteristics and a memory switching phenomenon were found in single-layer sandwich structures (ITO/polymer/Al, Au/polymer/Al). In air the anomalous behaviour disappeared. Microcavity effects in the electroluminescence emission of the single-layer devices are further reported.
