Abstract :
Recently, we investigated the time dependence of EL intensity under ac voltage application. Light intensity changed with time. It was found that degraded region is formed around the point electrode after, ac voltage application. We consider that time changing EL intensity reflects changes in the polymer molecular structure. In the present paper, we will report the results of the recent investigation
