Lithium characteristic x-ray

Web15 mrt. 2024 · The quantification of lithium in electron microscopes by energy-dispersive X-ray spectroscopy (EDS) is highly challenging due to the low energy of the characteristic … Web28 feb. 2005 · Not only characteristic x-ray line emission is generated by electron beam excitation, but also a continuous spectrum originating from the deceleration of the electrons in the sample material. The so called “bremsstrahlung” superimposes the characteristic emission reducing the Peakto- Background ratio and thereby the sensitivity for traces.
