The notions of nanoscale "phase speciation" and "phase diagram" are defined and discussed in terms of kinetic and thermodynamic controls, based on the case of metal phosphide nanoparticles. After an overview of the most successful synthetic routes for these exotic nanomaterials, the cases of InP, Ni2 P, Ni12 P5 and Pdx Py are discussed in detail to highlight the relationship between composition, structure, and size at the nanoscale. The influence of morphology is discussed next by comparing the behavior of Cu3 P nanophases with those of Nix Py , FeP/Fe2 P, and CoP/Co2 P. Perspectives provide the reader with methodological guidelines for further investigation of nanoscale "phase diagrams", and their use for optimized synthesis of new functional nanomaterials.
本文从动力学和热力学控制的角度，定义并讨论了纳米级“相态分类”和“相图”的概念，以金属磷化物纳米粒子为例。在概述了这些奇异纳米材料最成功的合成途径之后，详细讨论了 InP、Ni2 P、Ni12 P5 和 Pdx Py 的情况，以突出组成、结构和纳米尺度大小之间的关系。接下来通过比较 Cu3 P 纳米相与 Nix Py、FeP/Fe2 P 和 CoP/Co2 P 的行为，讨论了形态的影响。展望为进一步研究纳米级“相图”以及将其用于优化新型功能纳米材料的合成提供了方法学指导。
