Abstract

All-inorganic Cd-based halides have attracted much interest as a unique class of metal halides because of their afterglow luminescent properties, although the photoluminescence quantum yield (PLQY) is relatively low (<10%). Here, we investigated the optoelectronic characteristics of all-inorganic Cd chloride, including CsCdCl₃, Cs₂CdCl₄, and Cs₃Cd₂Cl₇, and improved their PLQY by Cu(I) doping, achieving a maximal PLQY of 81.6 ± 1.5% for Cs₃Cd_1.96Cu_0.04Cl_6.96. Based on the improved optoelectronic properties, we further used them for X-ray detection and anticounterfeiting. Under continuous X-ray irradiation at a dose rate of 26.5 Gy/min for 1800s, the Cu(I) ion-doped Cd chloride exhibits bright luminescence with little intensity loss, indicating high X-ray resistance and stability. As for anticounterfeiting, diversified modes have been fabricated, showcasing the versatile applications of Cd chloride with tunable persistent luminescence in advanced security systems. Our work demonstrates that multimodal luminescence makes Cd-based chlorides suitable as a unique choice among metal halides, extending the applications of metal halides across a wide range of optoelectronic fields.

氯化铯镉掺杂增强光致发光在x射线检测和防伪中的应用

全无机镉基卤化物作为一类独特的金属卤化物，虽然其光致发光量子产率（PLQY）相对较低（10%），但由于其余辉发光特性而引起了人们的广泛关注。本文研究了CsCdCl3、Cs2CdCl4和Cs3Cd2Cl7等全无机氯化镉的光电特性，并通过Cu(I)掺杂提高了它们的PLQY， cs3cd1.96、cu0.04、cl6.96的PLQY最大可达81.6±1.5%。基于改进的光电性能，我们进一步将其用于x射线检测和防伪。在26.5 Gy/min剂量率的连续x射线照射下，Cu(I)离子掺杂的氯化镉发光明亮，强度损失小，具有较高的x射线抗性和稳定性。在防伪方面，已经制作了多种模式，展示了具有可调谐持久发光的氯化镉在先进防伪系统中的广泛应用。我们的工作表明，多模态发光使得基于cd的氯化物适合作为金属卤化物的独特选择，扩展了金属卤化物在广泛光电领域的应用。
