Organic–inorganic hybrid copper(I)-based metal halides (OIHCMHs) have emerged as promising alternatives to lead perovskites due their exceptional optical properties. However, the lack of low-energy light-emitting compounds prohibits further applications. Herein, we report an orange–red emissive (C 19 H 18 P) 2 Cu 4 Br 6 with a zero-dimensional structure. The photoluminescence (PL) peak locates at 640 nm PL quantum yield 69.3%, and large Stokes shift is 245 nm. Experimental analyses demonstrate bright broadband light emission derived from synergistic effect metal-to-ligand charge transfer or halide-to-ligand (MLCT/HLCT) excited state cluster-centered (CC) state. Furthermore, can be used phosphor for didoes (LEDs), by adding other blue- cyan-emitting phosphors, white LED high color rendering index over 94 achieved. This work not only demonstrates material design strategies preparing OIHCMHs but also inspires potential low-dimensional in quality

Abstract Cu(I)‐iodide clusters have attracted broad attention due to their outstanding photoluminescence properties. However, commercial viability is often constrained by moderate quantum yields. In this work, a solid solution strategy employed synthesize heterometallic cluster 3·Cu/Ag , achieving nearly 18‐ and 10‐fold enhancements in yield (up 86.10%) relative the monometallic 1·Cu 2·Ag respectively. Detailed investigations reveal an unprecedented mechanism balancing energy migration thermal quenching, which underlies intense emission distinct thermochromic behavior of under both cryogenic ambient conditions. These findings highlight potential applications luminescent thermometer, multicolor displays, solid‐state lighting technologies.
