Journal ArticleDOI
Energy transfer processes in CeF3 single crystals
TL;DR: In this article, the temperature dependences of regular and disturbed Ce3+ site emission and decay kinetics were investigated in temperature range 4.2 -300 K with the aim to determine the nature of the energy transfer mechanism in CeF3.
Journal ArticleDOI
Further results on GdAlO3:Ce scintillator
J. A. Mareš,Martin Nikl,C. Pedrini,D. Bouttet,Christophe Dujardin,Bernard Moine,J. W. M. Verweij,J. Kvapil +7 more
TL;DR: In this paper, spectroscopic properties of Ce3+ ions in GdAlO3 crystal are presented, and at least three nonequivalent centres (multisites) are present in this crystal.
Journal ArticleDOI
Luminescence and relaxed excited state origin in CsI:Pb crystals
TL;DR: In this article, the origin of the excited states responsible for the optical characteristics of CsI:Pb has been discussed and it has been concluded that the doublet ≈3.70 eV absorption (excitation) band is caused by the electronic transitions into the Pb 2+ triplet state split due to the presence of a cation vacancy near a Pb2+ ion, while the higher energy bands are of the charge-transfer origin.
Journal ArticleDOI
Time-resolved photoluminescence and excited state structure of Bi3+ center in YAlO3
A. Krasnikov,L. Lipińska,E. Mihokova,Martin Nikl,T. Shalapska,Andrzej Suchocki,S. Zazubovich,Ya. Zhydachevskii,Ya. Zhydachevskii +8 more
TL;DR: In this article, an intense dominant ultraviolet luminescence of YAlO 3 :Bi is shown to arise from the radiative decay of the metastable and radiative minima of the triplet relaxed excited state (RES) of Bi3 + centers related to the 3 P 0, 3 P 1 levels of a free Bi 3+ ion, respectively.
Journal ArticleDOI
Gamma spectroscopy and optoelectronic imaging with hybrid photon detector

TL;DR: Hybrid Photon Detectors (HPDs) detect light via photocathodes and accelerate the emitted photoelectrons by an electric field towards silicon PIN-anodes, where they are absorbed and generate electronic signals as mentioned in this paper.
