- Abstract
- We demonstrated the influence of the air on blue phosphorescent organic light-emitting diodes by exposing the position of organic layers for various ambient exposure times to construct the disordered organic-organic interface in this work. To compare the effects of each hole and electron transporting path, organic layers were exposed according to the exciton blocking layer and emitting layer. Then we analyzed electrical and morphological properties using current-voltage-luminance measurement as well as other electrical and chemical analysis, such as impedance spectroscopy and X-ray photoelectron spectroscopy.
