| 英文摘要 | High color stability and CRI (>80) pure exciplex WOLEDs with merely complementary colors of orange-and blue-exciplexes are realized with the application of spacers. The WOLEDs with a three spacer structure achieve a maximum current efficiency, power efficiency and external quantum efficiency (EQE) of 16.2 cd A(-1), 11.3 lm W (-1) and 7.92%, respectively. Besides, a standard white light point close to Commission Internationale de l'Eclairage (CIE) coordinates of (0.31 +/- 0.00, 0.37 +/- 0.02) and a very high color rendering index (CRI) of similar to 83 with two colors emitting are obtained simultaneously. The balanced emission and natural broad emission band of the exciplex are responsible for the stable white light spectra and high CRI. We also find that the location of the spacers, and the amount of them, play a key role in the electroluminescence performance of the WOLEDs and more detailed discussions are given below. |
