X-ray fluorescence - Wikipedia
In simple terms, it works by illuminating a sample with high-energy X-rays, causing the atoms within to become excited and emit their own unique, characteristic X-rays—a process similar to how a blacklight makes certain colors fluoresce.

What is XRF (X-ray fluorescence) and How Does it Work?
Each of the elements present in a sample produces a set of characteristic fluorescent X-rays (“a fingerprint”) that is unique for that specific element, which is why XRF spectroscopy is an excellent technology for qualitative and quantitative analysis of material composition.

X-Ray Fluorescence (XRF) - Techniques
An X-ray fluorescence (XRF) spectrometer is an x-ray instrument used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that are similar to an electron microprobe (EPMA).

X-Ray Fluorescence Spectroscopy - an overview - ScienceDirect
X-ray fluorescence (XRF) spectroscopy is defined as a high-energy analytical technique that provides information about the elemental composition of a sample by analyzing the x-ray radiation emitted when incident x-ray radiation interacts with the target material.

Principle of XRF Analysis : Hitachi High-Tech Corporation
X-ray fluorescence analysis can be thought of as spectrochemical analysis within an X-ray region. It has the same characteristics as atomic absorption spectrometry and optical emission spectrometry except that the sample does not need to be dissolved in a solution to be analyzed.
