Tóm tắt

 Chiral metal clusters have promise for circularly polarized luminescent materials
  however, the absence of a unified understanding of the emission mechanism causes challenges in designing high-efficiency lighting materials based on these clusters. These challenges primarily arise from their vast structural variability and intricate emissive states. In this study, we show the crucial roles of the exciton binding energy and electron‒phonon interactions in achieving high-efficiency phosphorescence. Through Cu doping in the Au
