X-Ray Fluorescence Elemental Imaging
Electronic Absorption and Luminescence
First published: 09 March 2023
Abstract
X-ray fluorescence (XRF) imaging is a valuable analytical technique that provides elemental distribution maps. XRF imaging can be categorized as scanning-type and non-scanning-type, that is full-filed XRF imaging using a two-dimensional X-ray detector. Advanced X-ray focusing optics produce a micro X-ray beam in the laboratory, leading to scanning micro-XRF analysis and XRF imaging. A confocal micro-XRF technique has been applied to visualize the elemental distributions in the samples. The fundamentals and applications of the scanning-type XRF imaging techniques are also introduced. Thereafter, two full-field XRF imaging techniques are explained, that is, wavelength-dispersive XRF (WDXRF) imaging and energy-dispersive XRF (EDXRF) imaging. In addition, the characteristics of these XRF imaging techniques are compared.
