Spectral information from minerals relevant for luminescence dating
TL;DR: In this article, a review of spectral features of luminescence from minerals used in dating and allied research is presented and possible links between luminance production in minerals and particular lattice defects are considered.
Journal ArticleDOI
Luminescence techniques: instrumentation and methods
TL;DR: In this article, the most commonly used luminescence stimulation and detection techniques are reviewed and information is given on recent developments in instrument design and on the state of the art in luminecence measurements and analysis.

Cathodoluminescence (CL) behaviour and crystal chemistry of apatite from rare-metal deposits
Ulf Kempe,Jens Götze +1 more
TL;DR: Apatite samples from rare-metal mineralization were investigated by a combination of cathodoluminescence (CL) microscopy and spectroscopy, microchemical analysis and trace element analysis.
Journal ArticleDOI
Structure and luminescence characteristics of quartz from pegmatites
TL;DR: In this article, pegmatite quartz from several localities in Norway and Namibia were investigated by cathodoluminescence (CL) microscopy and spectroscopy, electron paramagnetic resonance (EPR) measurements, and trace-element analysis (ICP-MS) to obtain information about their structure and luminescence characteristics.
Journal ArticleDOI
Feldspar radioluminescence: a new dating method and its physical background
TL;DR: In this article, a new luminescence dating method based on radioluminescence measurements of potassium feldspar was proposed, where the light emitting transition of electrons from the conduction band into an optically sensitive electron trap was investigated for the first time.

Light-induced emission spectra from some quartz and feldspars
TL;DR: Some luminescence spectra in the range 300-600 nm relevant to optical dating are reported in this paper, where the authors separated from the south-east South Australian dune sequence gave a single emission band at 365 nm with a width of 60 nm, quite different from the ≈350°C thermoluminescence (TL) spectra of the same material.

Spectral measurement during thermoluminescence—an essential requirement
P.D. Townsend,Yoram Kirsh +1 more
TL;DR: Emission spectra recorded during thermoluminescence provide a fuller understanding of defect properties and, as detailed changes in spectra occur with dose, dose rate and thermal treatments, knowledge of emission spectra will make even simple radiation dosimetry, as well as applications such as archaeological and geological dating, more reliable as discussed by the authors.
Journal ArticleDOI
Some quartz thermoluminescence spectra relevant to thermoluminescence dating
TL;DR: In this article, a new high-sensitivity spectrometer was used to study the thermoluminescence spectra of several quartzes and the dependence of the spectra on radiation dose were examined for both laboratory dose and natural dose, which differ by 9 orders of magnitude in dose rate, and no effect due to dose rate was observed.

Thermoluminescence emission spectrometer
TL;DR: A sensitive thermoluminescence emission spectrometer based on Fourier transform spectroscopy is described, sufficiently sensitive to record thermolUMinescence spectra of dosimeter phosphors and minerals for thermolumscence dating at levels corresponding to those found during actual use as radiation monitors or in dating.
