在纳米介观尺度范围内实现对材料尺寸与形貌的调控,是纳米材料合成、制备、功能化及其应用的关键,对认识并解纳米晶的成核与生长规律具有重要意义.基于单分散氟化物纳米晶合成提出的扩散控制动力学模型(DCK,diffusion-controlled kinetic)和表面化学热力学模型(SCT,surface chemical thermodynamics)旨在探讨纳米晶的成核与生长规律.本文围绕纳米晶的成核、生长机理,在综述前人工作的基础上,归纳和总结了上述模型,有望对纳米晶的可控合成提供理论指导与借鉴.
It is of great significance to synthesize, prepare, functionalize and apply nanomaterials to control the size and topography of nanomaterials in the mesoscopic scale of nanometer scale. It is of great significance to recognize and resolve the nucleation and growth rules of nanocrystals. The diffusion-controlled kinetic model (DCK) and surface chemical thermodynamics (SCT) proposed by the synthesis of dispersed-fluoride nanocrystals are intended to investigate the nucleation and growth of nanocrystals. Nucleation and growth mechanism. Based on the review of previous work, the above models are summarized and summarized, which is expected to provide theoretical guidance and reference for the controlled synthesis of nanocrystals.
