In XRF, crosstalk refers to interference caused by which phenomenon?

Crosstalk in XRF happens when emission lines from different elements overlap in energy, and the detector can’t perfectly separate their signals. Because XRF detectors have finite energy resolution, lines that are close in energy can bleed into each other, causing counts attributed to one element to appear in the window for another. This leads to misidentification and biased quantification unless corrected, for example by using higher-resolution detectors or spectral deconvolution and tuning energy windows. Electrical noise, sample heating, and ambient light are not about crosstalk between elements’ X-ray lines. Electrical noise affects overall signal quality, heating can change emission intensity or background, and ambient light doesn’t influence the enclosed XRF detector system.
