Paper Abstract

AC electroluminescence from organic thin film electroluminescent (OTFEL) devices based on polymer poly(p- phenylene-vinylene) and molecular compound tris(8- hydroxyquinoline) aluminum (Alq3)was observed. The emission spectra of these devices driven by ac were recorded. The current-voltage (I-V) and brightness-voltage (B-V) were measured. It shows that the performances of OTFEL devices which were driven by ac is as good as those driven by dc. It opens a new application field that organic thin film electroluminescent devices can be driven by both dc and ac.
