Copper(I) halides are promising candidates for advanced optoelectronics, such as white-light-emitting diodes (WLEDs), scintillators, and photodetectors. Designing synthesizing low-dimensional hybrid copper with blue-light excitation remains an enormous challenge. Herein, we have prepared two one-dimensional (1D) Cu(I)-based metal iodides, namely, (C6H7N)CuI (C6H8N)CuI2 single crystals, by deliberately adjusting the ratio of reactants 4-methylpyridine (4-MePy) CuI. crystals nonluminous, while exhibit unusual yellow emission a broad band in range 260-500 nm Furthermore, prototypical WLED is fabricated combining commercial 430 blue chip phosphor, which exhibits correlated color temperature (CCT) 5645 K CIE coordinate (0.329, 0.334), thus demonstrating potential application white lighting. Remarkably, emit red fluorescence upon adsorption methanol but fail all other alcohols. Notably, initial luminescence can be recovered volatilization from achieving reversible photoluminescence switching. This work not only presents important reference blue-light-excitable iodide phosphor WLEDs also provides intriguing sensor detection methanol.
