Photosynthesis Research, 2009
Thermoluminescence (TL) probes the emission of luminescence associated with the de-trapping of a radical pair as the temperature is increased. This technique has proved useful for characterizing the energetic arrangement of cofactors in photosynthetic reaction centers.

Thermoluminescence: experimental
Photosynthesis Research, 2009Thermoluminesence measurements are useful for the study of Photosystem II electron transport in intact leaves, in algal and cyanobacterial cells, as well as in isolated membrane complexes. Here an overview of the experimental approaches is provided.

Thermoluminescence and thermoluminescence spectra of synthetic fluorapatite
Journal of Luminescence, 1980Abstract On account of their fairly long life, alkaline earth halophosphate phosphors are still the mainstay of the fluorescent lamp industry. For higher efficiency and an increased selection of spectral distribution, with minor variation in composition and dopants, halophosphates are synthesised nowadays.

Thermoluminescence of Lunar Samples
Science, 1970Appreciable natural thermoluminescence with glow curve peaks at about 350 degrees centigrade for lunar fines and breccias and above 400 degrees centigrade for crystalline rocks has been recognized in lunar samples. Plagioclase has been identified as the principal carrier of thermoluminescence, and the difference in peak temperatures indicates ...

Thermoluminescence of Biological Materials
Nature, 1970THERMOLUMINESCENCE may be observed from many chemical compounds, both in crystalline and in amorphous form. The compounds so far investigated have usually been mineral or synthetic materials, but there is no reason to suppose that the various salts deposited in biological materials have a structure excluding this property.

Thermoluminescence of Biological Materials
Nature, 1971THERMOLUMINESCENCE (TL) of fossil bones and of various kinds of recent biological material has been reported by Jasinska and Niewiadomski1, who suggest that such materials could be used for dating purposes, but draw attention to difficulties which arise due to tribothermoluminescence (TTL, which is thermoluminescence derived from the mechanical energy ...

On the Thermoluminescence Characteristics of NAF and KCL
Applied Radiation and Isotopes, 2023Thermoluminescence (TL) properties of NaF and KCl are investigated in order to assess their suitability as radiation dosemeters for retrospective dosimetry. TL measurements were made on samples irradiated to different doses (1-20 Gy) and heated at a rate ranging from 0.4 to 4 °C/s in a TL/OSL reader.

Analysis of Thermoluminescence of Topaz
Physica Status Solidi (a), 1984Thermoluminescence (TL) of RT (30 °C) X-irradiated topaz shows five TL peaks in the range 30 to 500 °C. Out of these, four peaks occurring at 101, 189, 238, and 336 °C can be isolated. The TL peak occurring in the region of 450 °C which is not yet reported in literature can not be isolated because of its low intensity and high black body radiation ...

Alumina as a Thermoluminescent Material
AIP Conference Proceedings, 2007Thermoluminescence dosimeters are extensively used for quantitative dose measurements in various irradiation fields. They are also important for environmental monitoring after nuclear accident and weapon tests. In this work, the principles of TLD dosimeter and characteristics of several TLD materials are presented.

Thermoluminescent Properties of Topaz
Health Physics, 1978AbstractThe possibility of using naturally occurring topaz crystals as a thermoluminescent dosimeter (TLD) was investigated. Topaz crystals are small, durable and possess thermoluminescent characteristics which compare favorably with existing commercial materials.
