Characteristics of Pulsed Blue and Green Light Stimulated Luminescence Signals of Quartz and Feldspars

Abstract The post-infrared (post-IR) pulsed blue light stimulated luminescence (PBLSL) signal has been employed to determine the equivalent dose (D e ) of feldspar contaminated quartz grains, but it sometimes suffers from interference feldspars. Since green (GLSL) feldspars might be more reduced by a prior IR stimulation, we compared characteristics post-IR PBLSL and GLSL (post-IR PGLSL) signals in this study evaluate feasibility employing for stimulation. We investigated effect integration period, stimulation temperature, temperature on intensities PGLSL feldspars, evaluated potential these two hypothetical artificial quartz-feldspar mixture. results demonstrate lower contribution signal. only slightly increases with increase period measured at low which permits long enhance noise ratio. This shows that is promising alternative suppress contribution.
