| 摘要: 晶核作为晶体生长过程中新相形成的开始，理解它们的性质和行为特点对纳米材料的控制合成有重要指导意义，尤其对形貌和尺寸的调控。可控合成的超小尺寸纳米晶(< 5 nm)为研究晶核的性质提供了一个理想模型。本文基于纳米晶核在纳米材料控制合成中的研究进展，论述了晶核的尺寸与表面结构对纳米材料生长与组装模式的影响，尤其是基于纳米晶核预组装途径的晶体生长模式。 |

| Abstract: Nucleus, the beginning of a new phase, underlies the understanding of various synthetic approaches of nanomaterials, especially for the control over their sizes and shapes. Ultrafine nanocrystals with sizes smaller than 5 nm provide ideal models to learn the properties and growth behaviors of nucleus. The size and surface effects of nucleus on the growth and assembly of nanostructures are discussed in this review paper, based on the syntheses of ultrafine nanocrystals, including semiconducting oxides, metals and rare earth oxide. A newly crystal growth pattern emphasizing the pre-assembly of nucleus are highlighted to show the thesis. |
