Dolomite luminescence thermochronometry reconstructs the low-temperature exhumation history of carbonate rocks in the central Apennines, Italy [PDF]

Communications Earth & Environment
The lack of available thermochronological methods has so far hampered reconstructions of the cooling and exhumation histories in carbonate rock regions. Here we develop a new trapped charge thermochronometry tool based on the thermoluminescence signal of

Estimate half-life of thermoluminescence signals according to the different models by using Python

Journal of Taibah University for Science, 2021
In this study, the half-life is the time required for the thermoluminescence intensity to drop to half of its initial value. The half-life is a characteristic of the optical and thermal properties of the material.

Disorder-enhanced luminescence kinetics in volcanic feldspars [PDF]

EPJ Web of Conferences, 2020
A granitic feldspar is well-ordered and has a stable thermoluminescence signal enabling its dating with high reliability. In contrast, a volcanic feldspar (sanidine) exhibits a slight cristallographic disorder and an anomalously fast fading of the ...

Suitability of pure nano crystalline LiF as a TLD dosimeter for high dose gamma radiation [PDF]

Nuclear Technology and Radiation Protection, 2018
LiF is an alkali halide that is commonly used in radiation dosimetry utilizing its well-known thermoluminescence property. Pure LiF has very limited use in radiation dosimetry since the density and types of the internal traps are limited.
