Synergistic Enhancement of Near-Infrared Emission in CsPbCl₃ Host via Co-Doping with Yb³⁺ and Nd³⁺ for Perovskite Light Emitting Diodes.

ABSTRACT: Perovskite nanocrystals (PeNCs) have emerged as a promising class of luminescent materials offering size and composition-tunable luminescence with high efficiency and color purity in the visible range. PeNCs doped with Yb³⁺ ions, known for their near-infrared (NIR) emission properties, have gained significant attention due to their potential applications. However, these materials still face challenges with weak NIR electroluminescence (EL) emission and low external quantum efficiency (EQE), primarily due to undesired resonance energy transfer (RET) occurring between the host and Yb³⁺ ions, which adversely affects their emission efficiency and device performance. Herein, we report the synergistic enhancement of NIR emission in a CsPbCl₃ host through co-dopin
