Ion beam-induced luminescence (IBIL) is a technique for materials analysis. An ion beam is used to excite atoms in a target, and visible light emitted from the target material is analyzed with a fiber-optic spectrometer. IBIL produces a spectrum from a matter-particles interaction. This luminescence spectrum can reveal the presence of ultra-trace chemical elements that would not otherwise be detected by PIXE and PIGE analyses.
