Abstract

Scintillator can convert ionizing radiation of high-energy ray or particle into ultraviolet/visible light, which is extensively employed for baggage screening and non-destructive testing applications. In this paper, transparent Tb³⁺-doped fluoroxide glass scintillators were fabricated successfully by melting quenching technique. Tb³⁺-doped fluoroxide glass possesses commendable luminescent properties. The optimal sample (SACNY-3Tb) has a high transmittance (87.6%@542 nm) and a suitable lifetime (2.24 ms). In addition, SACNY-3Tb has good scintillating properties. The X-ray excited luminescent intensity of SACNY-3Tb is 130% of that of Bi₄Ge₃O₁₂, and 18 lp/mm of imaging resolution for X-ray can be obtained. In conclusion, the Tb³⁺-doped fluoroxide glass scintillator possesses potential for use within the application of steady-state X-ray detection.

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.
