High Color-Rendering Index and Stable White Light-Emitting Diodes by Assembling Two Broadband Emissive Self-Trapped Excitons

Zhuangzhuang Ma et al.

Summary: This study introduces a two-component strategy using two broadband emissive materials with self-trapped excitons (STEs) to produce high CRI and stable WLEDs. By synthesizing copper-based ternary halides composites, the research demonstrates cold/warm tunable WLEDs with high CRI and excellent stability. These results highlight the potential of using hybrids of STEs-derived broadband emissive materials for high-performance WLEDs.
