标题： Nanodiamond arrays on glass for quantification and fluorescence characterisation

摘要： 量化荧光纳米金刚石的发射特性对于开发其广泛的应用性非常重要。 定向自组装技术显示出将纳米金刚石精确定位的潜力，从而实现这种量化。 在这里，我们展示了一种将纳米金刚石沉积在预先确定的阵列中的方法，这些阵列用于收集关于荧光寿命的统计信息。 这些阵列是通过使用电子束光刻对光刻胶层进行图案化处理，形成孔径网格而创建的，然后滴加纳米金刚石。 电子显微镜显示，在3,376个填充的阵列位点中，平均沉积率为90%，每个位点平均有20个纳米金刚石。 共聚焦显微镜优化了氮空位荧光收集，显示荧光寿命分布广泛，与文献一致。 这种方法对于统计量化荧光纳米颗粒提供了迈向用于从量子密码学到传感等应用的混合光子器件制造的重要一步。 显示英文摘要

摘要： Quantifying the variation in emission properties of fluorescent nanodiamonds is important for developing their wide-ranging applicability. Directed self-assembly techniques show promise for positioning nanodiamonds precisely enabling such quantification. Here we show an approach for depositing nanodiamonds in pre-determined arrays which are used to gather statistical information about fluorescent lifetimes. The arrays were created via a layer of photoresist patterned with grids of apertures using electron beam lithography and then drop-cast with nanodiamonds. Electron microscopy revealed a 90% average deposition yield across 3,376 populated array sites, with an average of 20 nanodiamonds per site. Confocal microscopy, optimised for nitrogen vacancy fluorescence collection, revealed a broad distribution of fluorescent lifetimes in agreement with literature. This method for statistically quantifying fluorescent nanoparticles provides a step towards fabrication of hybrid photonic devices for applications from quantum cryptography to sensing.
