在本文中，我们展示了有机发光二极管 (OLED) 中具有由一对介电镜和金属镜定义的平面微腔的强定向纯红色、绿色和蓝色发射。通过仔细控制腔模式和谐振波长的位置，微腔OLED实现了前向的强方向性以及光谱窄化和强度增强。与非腔OLED相比，谐振波长处的强度增强为1.5-5，并且发射颜色的色品坐标是理想的原色。将实验结果与理论计算结果进行比较。
In this article we demonstrate strongly directed pure red, green, and blue emissions in the organic light-emitting diodes (OLEDs) with a planar microcavity defined by a pair of dielectric mirror and a metal mirror. By careful control of the cavity mode and the position of the resonance wavelength, the strong directionality in the forward direction as well as the spectral narrowing and the intensity enhancement are realized in the microcavity OLEDs. The intensity enhancements at the resonance wavelength are 1.5–5 compared to the noncavity OLEDs, and the chromaticity coordinates of the emission colors are the ideal primary colors. The experimental results are compared to theoretically calculated ones.
