摘要

有机发光二极管（Organic light emitting diode，OLED）作为新一代显示技术已经成功产业化，但兼具高效率和长寿命的蓝光OLED仍是亟待解决的问题。近年来，采用热活化延迟荧光（Thermally activated delayed fluorescence， TADF）材料敏化窄光谱荧光染料的热活化敏化荧光（TADF sensitized fluorescence，TSF）机制日益受到广泛关注。随着发光材料和器件结构的不断创新，基于该机制的蓝光OLED器件性能显著提升。本文围绕稳定高效蓝光敏化剂分子的设计开发，综述了近年来蓝光TSF器件在效率与寿命方面的进展，并进一步讨论了未来的发展目标以及面临的挑战。

Abstract

As a new generation of display technology， organic light emitting diodes （OLEDs） have been successfully commercialized， but efforts are still needed to develop efficient and stable blue OLED devices. In recent years， a new mechanism combining thermally activated delayed fluorescence （TADF） sensitizers and narrow spectrum final emitters， namely TADF sensitized fluorescence （TSF） has attracted more and more attention. With the continuous innovation of materials and device structures， performances of blue OLEDs based on this mechanism have been significantly improved. Here， focusing on the development of stable and efficient blue sensitizers， the progress in efficiency and lifetime of blue TSF devices in recent years is reviewed， and the future development goals and challenges are further discussed.
