Study on hybrid blue organic light emitting diodes with step controlled doping profiles in phosphorescent emitting layer
Abstract
We have designed blue organic light emitting diodes (OLEDs) consisting of fluorescent and phosphorescent emitters whose phosphorescent emitting layers have three step-controlled doping profiles of 0, 4 and 8%. The different doping profiles determined the characteristics of electroluminescent and fluorescent intensity variation under various voltages. Also, it was found that emission channels separated by the non-doped region enhanced …
