Proton induced luminescence of minerals
This paper presents a summary of Ionoluminescence (IL) for several minerals commonly found in jewellery pieces and/or artefacts ofhistorical interest. Samples including silicates and non-silicates (native elements, halide, oxide, carbonate and phosphate groups) have beenexcited with a 1.8 MeV proton...

| Sumario: | This paper presents a summary of Ionoluminescence (IL) for several minerals commonly found in jewellery pieces and/or artefacts ofhistorical interest. Samples including silicates and non-silicates (native elements, halide, oxide, carbonate and phosphate groups) have beenexcited with a 1.8 MeV proton beam, and IL spectra in the range of 200- 900 nm have been collected for each one using a fiber optic coupledspectrometer. Light emissions have been related to Cr 3+, Mn2+ and Pr3+ ions, as well as intrinsic defects in these minerals. Results showthe potential of IL for impurity characterization with high detection limits, local symmetry studies, and the study of the origin of minerals |
