4 Nanoparticles EDX Analysis The chemical composition of the prepared sample was analyzed using EDX analysis as shown in Fig.1.The lines observed at 5.90, 6.52, and 0.64 keV are associated for K (α, β) and L lines of the Mn element, respectively. In the EDX experiments, the intensity of Pd and Pt can be separately evaluated; hence, the number of shell layers was more clearly determined from the EDX analysis than from the HAADF–STEM image simulations. The EDX line at 0.52 keV represents K line of the O element. Imaging nano-objects in complex systems such as nanocomposites using time-of-flight secondary ion mass spectrometry (TOF-SIMS) is a challenging task.
