Abstract

Hybrid Cu(I)-based halides have been widely studied in the field of optoelectronics due to their outstanding optical properties as well as their remarkable structural diversity, however, the complicated synthetic method and poor stability hampered Cu(I)-based metal halides practical applications. Herein, a new zero-dimensional (0-D) hybrid copper iodide (Cu₂I₂(3,4-DMP)₄ (1, 3,4-DMP = 3,4-Dimethylpyridine) has been synthesized by ionothermal reaction. Under UV irradiation, 1 shows cyan emission with photoluminescence quantum yields (PLQY) as high as 80.07 %. In addition, 1 exhibits high antiwater stability, the photoluminescence (PL) and the radioluminescence (RL) intensity of 1 both above 80 % of the original ones when stored in water for 90 days. At room temperature, 1 shows an effective light yield of 38,031 photons/MeV and a sensitive X-ray response, with a detection limit as low as 106.71 nGy/s, significantly below the dose required for medical diagnostics (5.5 μGy/s). Based on the above excellent performance, (Cu₂I₂(3,4-DMP)₄ can be used as fluorescent inks for aerosol jet printing (AJP). This study provides a new avenue for designing multifunctional materials and application of non-toxic hybrid metal halides.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
