[OLED1-3L (Invited)] Highly Efficient and Pure Blue Fluorescent Organic Light-Emitting Diodes with Excellent Device Stability
high efficiency blue fluorescent OLED, excellent stability, triplet-triplet annihilation, Triazine derivative
Blue fluorescent organic light-emitting diodes with a high external quantum efficiency of 9.53% and excellent lifetime (LT95 ~1335 h) at 1000 cd/m2 are demonstrated. The LT95 is further enhanced to 3450 h in the device with a triazine derivative used as an electron transport layer.
