Effect of polymer layer morphology by thermal treatment on I-V characteristics of electroluminescence device

초록

The morphology change of polymer HTL by thermal treatment is investigated, which affects the performance of organic light emitting diodes (OLEDs). OLEDs are fabricated with the structure of ITO/Polymer HTL/Emitting layer (Alq(3))/Electrode (Al). The polymer HTL layer was treated by heat, which causes the morphology change like the aggregation of polymer HTL. The aggregation of polymer HTL due to the heal affects the rum-on voltage and lifetime of OLED.
