Abstract

Low-dimensional metal halides have emerged as promising anti-counterfeiting materials. However, achieving a multi-mode and multi-color anti-counterfeiting system in metal halides remains challenging. In this study, copper-halide (TBP)2Cu4Br6 (TBP+ = C16H36P+) single crystals are synthesized using a cooling crystallization method, which exhibits efficient dual-band emissions (542 and 708 nm), large Stokes shifts (282 and 330 nm), and a high photoluminescence quantum yield (PLQY) of 92.7% for 542 nm. These exceptional properties are attributed to the unique 0D structure of (TBP)2Cu4Br6 single crystals, which facilitates the formation of two different self-trapped excitons (STEs). Furthermore, based on (TBP)2Cu4Br6, a multi-mode and multi-color digital anti-counterfeiting system integrated is designed with Morse code information encryption, demonstrating promising applications in information security and anti-counterfeiting. This work not only illustrates an emitter in copper halides but also paves the way for achieving multi-mode and multi-color anti-counterfeiting systems.

激发波长诱导的卤化铜双波段荧光在多模式加密和防伪中的应用
低维金属卤化物已成为很有前途的防伪材料。然而,在金属卤化物中实现多模式、多色防伪系统仍然具有挑战性。本研究采用冷却结晶法合成了卤化铜(TBP)2Cu4Br6 (TBP+ = C16H36P+)单晶,该单晶具有高效的双波段发射(542和708 nm),大的Stokes位移(282和330 nm), 542 nm的光致发光量子产率(PLQY)高达92.7%。这些特殊的性质归因于(TBP)2Cu4Br6单晶独特的0D结构,这有利于形成两种不同的自捕获激子(STEs)。此外,基于(TBP)2Cu4Br6,设计了集成摩尔斯电码信息加密的多模多色数字防伪系统,在信息安全和防伪方面具有广阔的应用前景。这项工作不仅展示了卤化铜的发射器,而且为实现多模式和多色防伪系统铺平了道路。
