本文介绍了一种高产率制备均匀荧光纳米金刚石的新方法。将通过荧光高压高温金刚石微晶的高能球磨获得的粉末转化为平均尺寸小于或等于10 nm的高度结晶的超小纳米颗粒的纯浓缩水性胶体分散体。胶体准球形纳米金刚石的整个制造产率比先前报道的从微米金刚石开始的那些高几个数量级。这些结果为具有良好控制性能的荧光纳米金刚石的工业成本效益生产开辟了途径。
A new fabrication method to produce homogeneously fluorescent nanodiamonds with high yields is described. The powder obtained by high energy ball milling of fluorescent high pressure, high temperature diamond microcrystals was converted in a pure concentrated aqueous colloidal dispersion of highly crystalline ultrasmall nanoparticles with a mean size less than or equal to 10 nm. The whole fabrication yield of colloidal quasi-spherical nanodiamonds was several orders of magnitude higher than those previously reported starting from microdiamonds. The results open up avenues for the industrial cost-effective production of fluorescent nanodiamonds with well-controlled properties.
