Ionizing-radiation-induced Scintillation Characteristics of Ti-doped SrZrO3 Single Crystal

Abstract

In this study, SrZrO 3 single crystals doped with 0, 0.3, 1.0, and 3.0% Ti were successfully synthesized by the floating zone method, and their optical and scintillation properties were investigated. Both the photoluminescence (PL) and scintillation spectra revealed a broad emission band centered at 400 nm, and the decay time constants were of µs order. All the Tidoped specimens exhibited clear full energy peaks under 241 Am α-ray irradiation. The obtained PL quantum yield and pulse height spectra suggest that the optimum Ti concentration among our specimens is 3.0%.

Investigation of K2Cu(Cl,Br)3 crystalline scintillators

“…Single crystalline scintillators have been extensively investigated [15][16][17][18][19][20] owing to their high optical properties and high homogeneity. For instance, the following crystals are representatively implemented in practice: Bi 4 Ge 3 O 12 (BGO), [21][22][23][24] CdWO 4 (CWO), [25][26][27] and Tl-doped NaI and CsI.…”

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.…”

Tm Concentration Dependence on Scintillation Properties of Y3Al5O12 Garnet Single Crystals

“…Therefore, the performance of scintillators strongly affects that of radiation detectors. Various scintillators, such as films, (6) ceramics, (7)(8)(9)(10)(11)(12) glasses, (13)(14)(15)(16)(17)(18)(19)(20)(21)(22) single crystals, (23)(24)(25)(26)(27)(28)(29)(30)(31)(32) and nanoparticles, (33) have been investigated to date. Single crystal materials tend to show excellent properties and are widely used as scintillators.…”
