本文描述了Au-Pd纳米粒子的内部结构，表现出新发现的三层核/壳形态，其由均匀合金化的内核、富Au的中间层和富Pd的外壳组成。通过利用空间分辨成像和透射电子显微镜（TEM）的光谱和衍射模式，获得了对所观察到的三个层中的每一个的组成的见解，这表明在monoclonal元素之间的紧密合金的显着程度。
This paper describes the internal structure of Au-Pd nanoparticles exhibiting newly discovered three-layer core/shell morphology, which is composed of an evenly alloyed inner core, an Au-rich intermediate layer, and a Pd-rich outer shell. By exploitation of spatially resolved imaging and spectroscopic and diffraction modes of transmission electron microscopy (TEM), insights were gained on the composition of each one of the observed three layers, indicating a significant extent of intimate alloy among the monometallic elements.
