Abstract

[Artikel-Nr.: 107596] Time-resolved luminescence measurements provide a powerful means of investigating luminescence processes across timescales, ranging from picoseconds to seconds. These measurements are typically enabled by pulsed stimulation, where light pulses of fixed durations are applied to a sample. Luminescence can then be recorded both during and after the pulsed light stimulation, allowing discrimination between stimulation and emission, as well as isolation of luminescence components with different lifetimes. Quartz and feldspar minerals are the two natural minerals most commonly used in luminescence studies. Time-resolved luminescence of feldspars has been investigated since the early 1990s, while quartz time-resolved signals has come into focus since around 2000. Over the past three decades, the extensive research into time-resolved and pulsed luminescence properties of these two minerals has provided insights into the lifetime of recombination and relaxation processes of various emissions in these minerals. These differences in the luminescence decay of quartz and feldspar offers a practical solution for discriminating their luminescence. This review is aimed at researchers specialising in the field of luminescence dating, who embark on their first pulsed and time-resolved luminescence journeys. It provides practical information on measurement techniques for conducting time-resolved luminescence measurements and presents an overview of research findings, accumulated over the past 3.5 decades highlighting both the fundamental processes revealed and the applications enabled by these methods.
