Scintillation and dosimeter properties of Tb-doped strontium fluoride transparent ceramics
Luminescence properties of strontium fluoride transparent ceramics with various TbF3 amounts (0.1, 0.5, and 1 %) were investigated. Scintillation peaks derived from the electronic transitions between 4f levels in Tb3+ were observed. The observed scintillation decay times of approximately 8.3 ms were typical for the electronic transitions in Tb3+. Furthermore, the Tb-doped strontium fluoride transparent ceramics showed thermoluminescence and optically stimulated luminescence (OSL) with Tb3+ serving as the recombination center. The most intense thermoluminescence signal was detected from the 0.1 % Tb-doped transparent ceramic within the range of 0.01–100 mGy. OSL stimulated by 600 nm light of the same material was the most intense, and its lowest detectable limit was about 100 mGy.
期刊介绍：
The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.
We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
