Exempel på hur man kan använda THERMOLUMINESCENCE i en mening

• It was also thought to exhibit pyrognomic properties, as it can emit visible light when heated to relatively low temperatures, but the scientific consensus is that this is the product of thermoluminescence.
• Doped calcium fluoride, like natural fluorite, exhibits thermoluminescence and is used in thermoluminescent dosimeters.
• The Rock Wren Biface, a large well-formed biface tool recovered from a younger nested-inset alluvial deposit at Calico: dated by sediment thermoluminescence (sediment TL) to 14,400 ±2,200 years ago.
• Allanite and gadolinite are examples of minerals which have been claimed to exhibit true pyrognomic properties but have since been shown to exhibit thermoluminescence.
• Currently used techniques are magnetostratigraphy, low temperature thermochronology, cosmogenic nuclides, radiocarbon, thermoluminescence, optically stimulated luminescence, and U-Th disequilibria.
• Student projects that survived the rigours of publishing covered a wide range of topics from accelerator depth profile dating of bones and teeth, seasonal dating of shells using oxygen isotopes, experimental archaeology, thermoluminescence dating of oven stones, physical analysis of pottery, trace element analysis of obsidian sources with XRF, dating of human bone with ESR, and diet reconstruction from atomic absorption spectroscopy of human bone.
• Chlorophane, also sometimes known as pyroemerald, cobra stone, and pyrosmaragd, is a rare variety of the mineral fluorite with the unusual combined properties of thermoluminescence, thermophosphoresence, triboluminescence, and fluorescence: it will emit light in the visible spectrum when exposed to ultraviolet light, when heated, and when rubbed; if heated, it will continue to emit light for a period of time after a heat source is withdrawn.
• Glass beads and Ge-doped optical fibres as thermoluminescence dosimeters for small field photon dosimetry.
• Chlorophane is unusual for combining the properties of thermoluminescence, triboluminescence, phosphorescence, and fluorescence; it will emit visible spectrum light when rubbed, or exposed to light or heat, and can continue emitting for a long period of time.
