Arrays of fluorescent nanoparticles are highly sought after for applications in sensing, nanophotonics and quantum communications. Here we present a simple and robust method of assembling fluorescent nanodiamonds into macroscopic arrays. Remarkably, the yield of this directed assembly process is greater than 90% and the assembled patterns withstand ultra-sonication for more than three hours. The assembly process is based on covalent bonding of carboxyl to amine functional carbon seeds and is applicable to any material, and to non-planar surfaces. Our results pave the way to directed assembly of sensors and nanophotonics devices.
荧光纳米粒子阵列在传感、纳米光子学和量子通信等领域有广泛的应用需求。在此，我们提出了一种简单而强大的方法，可将荧光纳米金刚石组装成宏观阵列。值得注意的是，这种定向组装过程的产率大于 90%，并且组装图案可承受超过三个小时的超声处理。该组装过程基于羧基与胺功能碳种子的共价键合，适用于任何材料和非平面表面。我们的研究结果为传感器和纳米光子学器件的定向组装铺平了道路。
