Description
We demonstrate that the visible/UV luminescence from common feldspar crystals (NaAlSi3O8, KAlSi3O8 and CaAl2Si2O8) can be used to detect detailed L-edge and associated near-edge absorption structure of the main constituent atoms (Ca, K, Na, Al, Si), when exciting in the energy range 20-500 eV. Comparisons of the spectral features are drawn with similar measurements made on the associated materials SiO2, Al2O3 and CaCO3. The potential for using optically detected x-ray absorption spectroscopy as a method for identifying the luminescent components of mixed mineral samples is considered
