Hybrid halocuprates (I) with organic cations show great potential for optoelectronic applications due to their tunable luminescence and high thermal stability. In this study, the iodocuprate [PPh4][Cu3I4], featuring unique helical chains of face-sharing tetrahedra, was synthesized characterized. This compound exhibits a bandgap 3.1 eV orange at low temperature, attributed self-trapped exciton emission. [PPh4][Cu3I4] demonstrates exceptional stability among hybrid decomposition above 380 °C, forming stable melt ~255 °C without Cu+ oxidation in ambient atmosphere.

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
