摘要/Abstract

摘要： 综述了近年来有机长余辉材料的研究进展。最近开发的有机余辉材料通过突破调制超快衰减的激发态的困难，在室温下显示出具有持久发光的长寿命发射，其寿命比常规荧光和磷光发射的寿命长几个数量级。讨论了通过不同策略（晶体诱导、重原子效应、氢键作用、自组装、主客体掺杂等）合成的有机余辉材料，由于其独特的性质（长的发光寿命、大的斯托克斯位移、容易的激发态跃迁和环境敏感的发射），进一步探讨了其在各个领域的应用前景。

Abstract: This paper reviewed the research progress in long afterglow materials in recent years. The organic afterglow materials were developed recently through breaking through the difficulty in modulating the excited state with ultra?fast decay and they exhibited long?life emission with persistent luminescence at room temperature. The lifetime of these developed organic afterglow materials was several orders of magnitude longer than that of conventional fluorescence and phosphorescence emission. The synthetic strategies of organic afterglow materials were also discussed， which included crystal induction， heavy atom effect， hydrogen bonding， self-assembly， host?guest doping， etc. Own to the unique properties of organic afterglow materials such as long luminescence life， large Stokes shift， easy excited state transition， and environment-sensitive emission， their application prospects in various fields were further discussed.

Key words: organic afterglow, luminous mechanism, optical applications
