摘要：
Metal halides with self-trapped exciton (STE-MHs) featuring broadband emission have manifested great potential in white light-emitting diodes (WLEDs) with encouraging progress proceeding at an exhilarating pace. In this Perspective article, the focus is on the key issues and challenges of STE-MH as the single-layered emitter in WLEDs after providing a brief introduction for STE and its working mechanism of the relevant white-light emission. Possible approaches and future research directions for efficient STE-MH-based WLEDs are also put forward, aiming at promoting their application in the next-generation high-quality solid-state lighting sources.
