Scope

This document describes the method of obtaining nano-scale core-shell material horizontal projection images and measuring their shell thickness (10 nm~100 nm) using transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM). This document is applicable to digital images of micro- and nano-particles recorded by TEM/STEM, as well as elemental surface distribution maps measured with an energy-dispersive X-ray spectrometer (EDS) or electron energy loss spectrometer (EELS). It is suitable for measuring the shell thickness of particles with a diameter ranging from 10 nm to 1 μm. This document is not applicable to particles with a Z-axis projection larger than the X-axis or Y-axis, or particles with complex geometric horizontal projection shapes, such as starfish-like nanoparticles. Note: The main reason is that when the measured shell thickness fluctuates by more than 20% of the minimum cross-sectional diameter, the uncertainty of this document will significantly increase.
