%X 在本文中，我基于空穴传输材料和电子传输材料形成的激基复合物制备了一系列单色和双色器件。通过改变两侧蓝激基复合物层的厚度，可以很容易地提高器件效率。在单色器件G1中实现了最大电流效率(CE)为11.66 cd/A，功率效率(PE)为11.14 lm/W，亮度高达12,570 cd/m<sup>2</sup>。优化的双色OLED器件B14的CE、PE和分别为，11.69 cd/A和14.81 lm/W。外量子效率(EQE)更是达到了5.95%，超过了传统荧光OLED的理论极限(5%)。这种简单的结构为以激基复合物为基础实现高效率低成本的OLED器件提供了一种新思路。<br />
In this paper, a series of monochromatic and bicolor devices are prepared based on exciplex formed by hole transport materials and electron transport materials. The device efficiency can be easily improved by changing the thickness of the blue exciter complex layer on both sides. A maximum current efficiency (CE) of 11.66 cd/A, a power efficiency (PE) of 11.14 lm/W, and a Luminance of up to 12570 cd/m2 are achieved in the monochrome device G1. The CE and PE values of the optimized two-color OLED device B14 are 11.69 cd/A and 14.81 lm/W, respectively. The external quantum efficiency (EQE) reached 5.95%, exceeding the theoretical limit of traditional fluorescent OLEDs (5%). This simple structure provides a new way to realize high efficiency and low cost OLED devices based on exciplex.
