Energy-Dispersive X-ray Spectroscopy (EDX)
In order to analyze the composition of the surface of components precisely, Mat-Tech utilizes Energy-Dispersive X-ray Spectroscopy (EDX). This is a surface analysis technique where an electron beam (emitting specific wavelengths of X-rays) strikes the component, thereby exciting an electron in an inner shell. This results in an electron hole in the electronic structure of the element.
The energy of the electron beam ranges from 10-20 keV. The amount of energy emitted in the form of X-rays depends on the element. The electron beam moves across the component, and the images are stored. The presence of Au, Ag, and Pd on the NP surface can be easily identified. However, elements with low atomic numbers are challenging to detect with EDX.
EDX can be used with very small components, even as small as a few cubic micrometers in size.
