17.10.2023New studies on the Secondary Fluorescence Effect
Dr. Xavier Llovet, the head of the electron microprobe laboratoryat CCiTUB, in collaboration with researchers from the Universitat Grenoble-Alps (France), has recently published a new article in the Microscopy and Microanalysis journal.
The research aims to elucidate how the secondary fluorescence effect impacts electron microprobe analyses conducted at a considerable distance (100 micrometers) from the boundary between two phases, even when the element of interest is exclusively present in the analyzed phase..
This work integrates experimental measurements, theoretical calculations, and Monte Carlo simulations, with a specific focus on the determination of the presence of nickel (Ni) in the mineral olivine. The nickel content in olivine is of significant importance in various fields, such as igneous petrology, where it serves as a petrogenetic indicator.
