摘要 胶体量子点由于具有高的量子效率、窄的激发光谱、独特的尺寸依赖激发光谱和良好的溶液加工兼容性等优异特性,在高色彩质量显示方面有着巨大的应用潜力。随着量子效率提升及电致发光原理、激子衰减机制、器件结构优化和电荷有效输运等研究的持续深入,QLED的发光效率从小于0.01%提升到20.5%,已接近商业化OLED的效率。从显示技术的长远发展来看,量子点电致发光显示将超越光致发光的量子点增亮膜和量子点彩色滤光片,有望成为下一代主流显示技术。根据“材料—器件—显示”的主线,依次对量子点材料发光特性和材料类别,以及发光器件的结构类型、发光机制和效率提升等方面展开概述,最后简要介绍了量子点电致发光显示的相关技术挑战和发展前景。

Abstract: Due to high quantum efficiency, narrow spectral emission, unique size-tunable spectra and excellent solution-processcompatibility, quantum dots have great potential in high-color-quality display. With deep exploration on mechanisms of excitation and attenuation, improvements of quantum yields, structural optimization of devices and effective transportation of charge carrier, external quantum efficiency of quantum-dot electroluminescent devices have been increased from less than 0.01% to about 20.5%, which is very close to the value of commercial OLEDs. In the long term,quantum-dot electroluminescent technology will transcend the photoluminescence brightness enhancement film and color filter products, and it is expected to become the next-generation display technology. Along with the link of “materials to device to panel”, this review first outlines the properties and categories of quantum dots. Next, the structures, types,mechanisms of devices are summarized. The key scientific and technological challenges of commercialization of quantum-dot display are finally identified.
