Radiation-induced Luminescence Properties of Ce-doped ZnBr2-based Glasses

Abstract

Ce-doped 20CsBr-20BaBr 2 -60ZnBr 2 glasses were synthesized by the conventional melt quenching method, and their photoluminescence (PL) and scintillation properties were investigated. In the PL and scintillation spectra, all the Ce-doped glasses showed broad emissions due to the 5d-4f transitions of Ce 3+ ions. Under 241 Am α-rays, the light yield of 0.05% Ce-doped glass was 40 photons/5.5 MeV-α.

Photoluminescence and Radioluminescence Properties of Y3Al5O12 Doped with 3d-Transition Metal Ions

“…Although many scintillators have been studied in the last few decades, (4)(5)(6)(7) fundamental studies on novel scintillators still continue to achieve better performance than ever before. There have been reports on various types of scintillator, such as single crystals, (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) nanocrystals, (22) crystalline films, (23) ceramics, (24)(25)(26)(27) glasses, (28)(29)(30)(31)(32)(33)(34)(35)(36)(37) plastics, (38) and organic-inorganic hybrid materials, (39)(40)(41)(42) even in the last few years. In terms of the luminescent center, specific dopants such as Ce, Eu, and Tl have been mainly used for commercial scintillators; however, other dopants are also of our interest.…”

Photoluminescence and scintillation properties of Pr-doped (Lu, Y)2Si2O7 crystals

“…6) The required properties for the scintillators vary for each application; however, high emission efficiency, fast decay, and low afterglow are generally important as scintillation properties. To explore the scintillators which satisfy the above requirements, various types of scintillators such as single crystals, [7][8][9][10] ceramics, [11][12][13] glasses, [14][15][16] and liquids [17][18][19] have been researched.…”

Optical and scintillation properties of Lumilass-G and -R glasses

“…In this research situation, a large number of new glasses have been studied for ionizing radiation detectors. [29][30][31][32][33][34][35][36][37][38][39][40] In the current study, we focused on commercial luminescent glasses, namely, Lumilass-G9 and -R7 by Sumita Optical Glass. Lumilass glasses were developed for general luminescent purposes, and luminescence colors of blue (Luminass-B), green (Lumilass-G9), and red (Lumilass-R7) were commercialized.…”
