TlSr2Br5: New intrinsic scintillator for X-ray and γ-ray detection

Exploring the optical properties of La2Hf2O7:Pr3+ nanoparticles under UV and X-ray excitation for potential lighting and scintillating applications

“…Scintillators are usually considered best if they possess various favorable properties such as high density, effective Z-number, emission output, energy resolution and radiation hardness in addition to being easy to grow in large quantities at low cost. 11 The systems comprised of the Ln 2 M 2 O 7 composition (Ln: trivalent lanthanides and M: tetravalent titanium group elements, such as Ti, Zr and Hf) have been explored extensively because of their various scientific and technological importance in various areas such as gas sensors, 12 thermal barrier coatings, 13 solid oxide fuel cells, 14 neutron absorbing materials 15 and nuclear waste hosts. 16 The structure plays a very crucial role for all the applications mentioned above and these compounds are known to exist as two structural variants, ordered pyrochlore and disordered fluorite structures, each having specific applications.…”

Advanced Halide Scintillators: From the Bulk to Nano

“…Substitution of an alkali metal with thallium results in better stopping power for high-energy γ quanta due to higher Z eff while keeping high performance. Therefore, analogs based on chlorides, [159] bromides, [160] and iodides [70,[161][162][163] were investigated. However, similarly to other Eu 2þ -doped scintillators mentioned, the iodides exhibit the best performance with LY up to 72 000 ph MeV À1 [163] and energy resolution below 3% (at 662 keV 137 Cs).…”

Improvements in scintillation performance of Tl2LaCl5:5%Ce single crystals via Sr2+, Ba2+ and Ca2+ co-doping

“…Most of the Tl-based halide scintillators have high light yield, good energy resolution, and fast decay time with Ce 3+ activation. 5 Some of the potential scintillators discovered in this class of materials include Tl 2 LiYCl 6 :Ce, [6][7][8] TLC:Ce (TLC), [9][10][11][12] TlSr 2 Br 5 , 13 TlCaCl 3 , 14 Tl 2 GdCl 5 :Ce, 15 Tl 2 LaBr 5 :Ce, 12,16 Tl 2 GdBr 5 :Ce, 17 TlSr 2 I 5 :Eu, [17][18][19][20] Tl 2 ZrCl 6 , [21][22][23][24][25] and Tl 2 HfCl 6 . 22,23,26,27 TLC is one of the most promising scintillators among the Tl-based halide scintillators.…”
