Second order kinetics thermoluminescence behavior of ky3f10 : ho3+ phosphor [PDF]

, 2020
The behavior of thermoluminescence glow curve properties of KY3F10 : H3+ o phosphor in view of second order kinetics was studied. Kinetic parameters of the glow curves used to determine the activation energy (E) the initial concentration of filled ...

Diverse lithologies in Bennu stones revealed using X‐ray computed tomography under pristine conditions

Meteoritics &Planetary Science, EarlyView.
Abstract The OSIRIS‐REx mission collected a 121.6 g regolith sample from the surface of asteroid Bennu. Preliminary examination (PE) was conducted jointly by JSC Curation and the OSIRIS‐REx Sample Analysis Team. To enable advanced, non‐destructive characterization during PE, 59 centimeter‐scale stones were individually scanned using X‐ray computed ...

Thermoluminescence of shocked granodiorite

, 1967
The Hardhat event was an underground nuclear detonation in granodiorite at the Nevada test site. Samples of this rock, representing all stages of peak shock pressure from zero to over 100 kilobars, were Investigated by thermoluminescence to determine ...

Mind the Bump: Thermal Quenching Correction of Thermoluminescence Glow Curves and Application to SrAl2O4:Eu2+, Dy3+

Advanced Photonics Research
In order to extract accurate information from a thermoluminescence glow curve it is necessary to correct it for thermal quenching. Assuming that the dominant quenching process is due to nonradiative deactivation, the correction can be made by the Mott ...

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

Induced thermoluminescence of X-ray irradiated nanostructured zinc oxide

, 2009
We report an in situ analysis of thermally stimulated luminescence (thermoluminescence, TL) of a sol–gel derived nanostructured ZnO. The quenching of thermoluminescence with Fe-doping in ZnO has also been investigated.

Systematic errors in thermoluminescence

, 2007
Thermoluminescence measurements potentially are distorted by a variety of systematic errors. Major difficulties are encountered with temperature values as there are inevitable temperature gradients which become more severe at higher heating rates ...

Thermoluminescence de quelques médicaments ionisés

, 2017
Thermoluminescence signals from ionized pharmaceuticals, as ampicillin, can be easily distinguished from those of untreated samples, even two years after radiolysis; thus they could be applied to the detection of a radio-sterilization ...
