This review presents an introduction to the synthesis of metallic nanoparticles by radiation-induced method, especially gamma irradiation. This method offers some benefits over the conventional methods because it provides fully reduced and highly pure nanoparticles free from by-products or chemical reducing agents, and is capable of controlling the particle size and structure. The nucleation and growth mechanism of metallic nanoparticles are also discussed. The competition between nucleation and growth process in the formation of nanoparticles can determine the size of nanoparticles which is influenced by certain parameters such as the choice of solvents and stabilizer, the precursor to stabilizer ratio, pH during synthesis, and absorbed dose.
本文综述了辐射诱导法（尤其是伽马射线辐照法）制备金属纳米粒子的方法。与传统方法相比，该方法具有一些优势，因为它可以完全还原并高度纯化纳米粒子，而无需使用副产品或化学还原剂，并且能够控制粒子的尺寸和结构。本文还讨论了金属纳米粒子的成核和生长机制。在纳米粒子的形成过程中，成核和生长过程的竞争可以决定纳米粒子的尺寸，而这受到溶剂和稳定剂的选择、前体与稳定剂的比例、合成过程中的 pH 值以及吸收剂量等因素的影响。
