Electron Paramagnetic Resonance and petrographic analysis for dating Mesolithic and Neolithic pottery from Al Khiday (Sudan)

open access: yes, 2016
Electron Paramagnetic Resonance (EPR) dating, like luminescence techniques, is based on the timedependent accumulation of trapped charges at mineral defect centres.

Use of optically detected magnetic resonance to correlate germanium electron centres with UV absorption bands in x-ray irradiated germanosilicate glasses

, 2000
The relationship between paramagnetic defect centres and UV absorption bands simultaneously generated by ionizing radiation in Ge-doped SiO2 glass is investigated using magneto-optical techniques.

Investigations on different measurement protocols of E` paramagnetic defect centres in quartz for provenance studies

, 2021
The sediment-routing concept [1] aims to integrate tectonic fluxes and climatically driven erosion, an approach that is at the core of modern studies into Earth-surface processes.

Structural, paramagnetic centres and luminescence investigations of the UV radiation-emitting BaZrO3:Gd3+ perovskite ceramic prepared via sol-gel route

, 2021
Perovskite-type ceramic materials have been widely studied due to their potential use in such applications as electrical, thermal, optical, and immobilizing host materials in nuclear waste. In this work, Gd3+-doped BaZrO3 perovskite samples were prepared

Paramagnetic Point Defect in Fluorine-Doped Silica Glass: The E^{'}(F) Center.

Physical Review Letters, 2023
Fluorine-doped silica is a key material used in all low-loss and/or radiation-resistant optical fibers. Surprisingly, no fluorine-related radiation-induced point defects have been identified.

Electron Paramagnetic Resonance Investigation of the Defect Responsible for Light- and Elevated-Temperature-Induced Degradation in Ga-Doped Czochralski Si

Photovoltaic Specialists Conference, 2023
In this work, we report electron paramagnetic resonance (EPR) spectroscopic study of the defect that causes light- and elevated-temperature-induced degradation (LeTID) in p-type Ga-doped Cz Si wafers.
