Effect of Secondary Fluorescence in Thin‐Film Thickness on Compositional Determination Using Electron Probe Microanalysis

open access: yesX-Ray Spectrometry, Volume 55, Issue 1, Page 184-189, January/February 2026.
ABSTRACT Unlike bulk analysis, thin film compositional analysis necessitates considering substrate effects, such as secondary fluorescence induced by x‐rays generated in the substrate and backscattered electrons. Several methods have been proposed to address these challenges.
