We report that constructed Au nanoclusters (NCs) can afford amazing white emission synergistically dictated by the Au(0)-dominated core-state fluorescence and Au(I)-governed surface-state phosphorescence, with record-high absolute quantum yields of 42.1% and 53.6% in the aqueous solution and powder state, respectively. Moreover, the dynamic color tuning is achieved in a wide warm-to-cold white-light range (with the correlated color temperature varied from 3426 to 24 973 K) by elaborately manipulating the ratio of Au(0) to Au(I) species and thus the electron transfer rate from staple motif to metal kernel. This study not only exemplifies the successful integration of multiple luminescent centers into metal NCs to accomplish efficient white-light emission but also inspires a feasible pathway toward customizing the optical properties of metal NCs by regulating electron transfer kinetics.

具有动态颜色调节功能的白光金纳米团簇组件

我们报告称，构建的Au纳米团簇（NC）可以在Au（0）主导的核心态荧光和Au（I）主导的表面态磷光的协同作用下产生惊人的白光发射，绝对量子产率创历史新高，达到42.1％水溶液和粉末状态下分别为53.6%和53.6%。此外，通过精心控制 Au(0) 与 Au(I) 物质的比例，可以在宽广的暖色到冷色白光范围（相关色温从 3426 到 24 973 K 变化）内实现动态色彩调节。以及从主基序到金属内核的电子转移率。这项研究不仅证明了将多个发光中心成功集成到金属NC中以实现高效的白光发射，而且还启发了一条通过调节电子转移动力学定制金属NC光学特性的可行途径。
