Thermoluminescence and optical absorption studies of natural grossular minerals
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The optical absorption spectra of two samples of grossular have been measured at room temperature. An intense charge transfer band (UVCT) of iron extends to the visible and near infrared region. Some peaks associated to ...
A comparative study of the thermoluminescence properties of several varieties of Brazilian natural quartz
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The following varieties of natural quartz, as the blue, the green, the red, the pink, the black, the sulphurous and the milky quartz, have been investigated concerning their thermoluminescence properties. For comparison ...
Correlation between thermoluminescence sensitivity and crystallization temperatures of quartz: Potential application in geothermometry
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The thermoluminescence (TL) characteristics of quartz are highly dependent of its thermal history. Based on the enhancement of quartz luminescence occurred after heating, some authors proposed to use quartz TL to recover ...
White and green jadeite characterization by thermoluminescence.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
Except for gemologically or industrially important silicate minerals, a large number of
other natural silicate minerals have been investigated only concerning
geological/mineralogical aspects. Jadeite is a silicate mineral ...
Thermoluminescence of aluminophosphate glasses in the metaphosphate composition
(Elsevier B.V., 2006-05-01)
Potassium aluminum phosphate (KAP) glasses in the system xKPO(3)-(100-x)AI(PO3)3 with x = 10, 30 and 50 mol% were prepared in the metaphosphate composition. The glasses were doped with MnO2 and their thermoluminescent (TL) ...
Trends in thermoluminescence date distributions for the Angostura micro region in Central Chile
(Elsevier, 2015)
This article presents a series of thermoluminescence dates obtained from archaeological sites in the Angostura micro region, at the southern edge of the Santiago basin, an area occupied by Bato and Llolleo groups during ...
Thermoluminescent kinetics for negligible retrapping: Its application to the analysis of the glow curve of Y2O3: Eu+3
(Elsevier, 2013-11-16)
In this article a novel algorithm for analysing glow peaks resulting from traps having negligible retrapping is reported. The algorithm features two advantages: (1) an expression for the light intensity has been derived ...
Interactive and non interactive multi-trap models in thermoluminescence: Closed expressions derived without approximations for analyzing glow curves
(Elsevier Science, 2017-12)
The kinetics usually employed for analyzing glow curves are either heuristic or derived from physical models resorting to approximations. In this article closed expressions for the interactive and non interactive multi-trap ...
