Abstract

Metal-free or purely organic phosphorescent materials (phosphors) with ultralong emission lifetimes have emerged as an important class of multifunctional materials with a wide array of applications. However, the mechanistic understanding of phosphorescence in purely organic emitters apparently lags behind practical accomplishments, and the existing knowledge has not been summarized properly. For example, despite the impurity effect on phosphorescence from metal-free organic emitters having been well-recognized for over a century, recent studies have rediscovered the critical role of impurities in the phosphorescence. Hence, this review aims at bridging the apparent knowledge gap by integrating prior understanding with the latest findings on the role of impurities in phosphorescence. In addition, purification methods of phosphors, methodologies to test for impurity-induced emission, and mechanistic considerations for impurity-induced phosphorescence are highlighted.

纯有机材料中的杂质诱导磷光

具有超长发射寿命的无金属或纯有机磷光材料（荧光粉）已成为一类重要的多功能材料，具有广泛的应用前景。然而，人们对纯有机发光体磷光的机理认识显然落后于实际成果，现有知识也没有得到很好的总结。例如，尽管杂质对无金属有机发射体磷光的影响早在一个多世纪前就已被广泛认识，但最近的研究重新发现了杂质在磷光中的关键作用。因此，本综述旨在通过将先前的理解与有关杂质在磷光中作用的最新发现相结合，弥补明显的知识差距。此外，还重点介绍了荧光粉的纯化方法、测试杂质诱导发射的方法以及杂质诱导磷光的机理考虑。
