초록
Highly stable organic electroluminescent devices have been achieved by treatment of thermal and electrical annealing. We investigate here the performance of theses devices at temperatures and pulse aging. We also demonstrate improved device stability due to thermal and electrical treatment, and the brightness decays at no treatment, thermal only, electrical only and thermal/electrical treatment were 86.6%, 89.5%, 93.0%, and 96.7%, respectively, in the after 150 h of operation driven with an initial luminance of
