Luminescence characteristics of muddy sediments in the turbidity maximum zone of the Yangtze River mouth and implications for the depositional mechanisms

Frontiers in Earth Science, 2022
Muddy sediments are the most prominent constituents of sedimentary successions in tide-dominated river deltas and have highly complex depositional mechanisms.

Thermally Transferred Optically Stimulated Luminescence, TT-OSL: a study on the responsible traps

Journal of Physics: Conference Series, 2022
Abstract Aim of this paper is to better investigate the Thermally Transferred Optically Stimulated Luminescence (TT-OSL) signal generated in quartz samples, both mineral quartz and quartz extracted from sediment, when they are heated after an optical bleaching. In recent years, TT-OSL has become an interesting dating technique because it

Recombination lifetimes of LiF:Mg,Cu,P for pulsed optically stimulated luminescence [PDF]

, 2021
The well-known thermoluminescent material LiF:Mg,Cu,P (MCP) was previously shown to emit significant optically stimulated luminescence (OSL). In this paper, we investigate the rate of OSL recombination processes in MCP, expressed as effective lifetimes ...

Luminescence properties of common salt (NaCl) available in Nigeria for use as accident dosimeter in radiological emergency situation

Journal of Radiation Research and Applied Sciences, 2017
In the event of a radiological accident or attack, it is important to assess and quantify radiation dose to the population. This could be done using materials in the vicinity that are sensitive to ionizing radiation.

Optically stimulated luminescence (OSL) as a chronometer for surface exposure dating [PDF]

Journal of Geophysical Research: Solid Earth, 2012
We pioneer a technique of surface‐exposure dating based upon the characteristic form of an optically stimulated luminescence (OSL) bleaching profile beneath a rock surface; this evolves as a function of depth and time. As a field illustration of this new method, the maximum age of a premier example of Barrier Canyon Style (BCS) rock art in Canyonlands ...
