This short perspective describes recent developments in the synthesis of nanoscale colloids from sparingly soluble precursors. These strategies, which we dubbed 'heterogeneous nanocrystal syntheses' owing to the presence of a precursor in a non-colloidal solid state, have demonstrated the ability to generate new colloidal shapes, a superior monodispersity and a remarkable ability to delay the onset of Ostwald ripening, when compared with more traditional and purely colloidal strategies. We review the key contributions to this emerging area of research and discuss in detail the remarkable number of differences between these syntheses and the widely used homogeneous organometallic syntheses for making nanoscale colloids.
这篇短文描述了近年来从难溶性前体制备纳米胶体的最新进展。由于前体处于非胶体固态,这些策略被我们称为“非均相纳米晶体合成”,与更为传统和纯粹的胶体策略相比,它们具有生成新胶体形状的能力、更好的单分散性和显著延缓奥斯特瓦尔德熟化的能力。我们综述了这一新兴研究领域的主要贡献,并详细讨论了这些合成方法与广泛使用的均相有机金属合成方法在制备纳米胶体方面的显著差异。
