Popis:	Feldspars are widely used as dosimeters in dating archaeological and geological materials by thermally or optically stimulated luminescence (TL, OSL). The TL, (IR)OSL and phosphorescence (following gamma irradiation) spectra of 26 samples covering the orthoclase-albite-anorthite ternary system, which were characterized by microscopy and X-ray diffraction analysis, were measured using the Freiberg high sensitive luminescence spectrometer. The range of observation for TL (up to 350°C) and phosphorescence was (200–800) nm. IR (880 nm) stimulated luminescence light has been detected between 330 nm and 660 nm. Representative examples of our systematic investigations on the luminescence behaviour of alkalifeldspars and plagioclases are presented.
