Effect of Ba substitution in CsSrI3:Eu2+

Recent R&D Trends in Inorganic Single‐Crystal Scintillator Materials for Radiation Detection

“…Eu-doped CsBa 2 I 5 and Cs(Sr , Ba)I 3 in the form of single crystals have been grown using the vertical Bridgman method, [86][87][88][89][90] where the CsBa 2 I 5 shows better tolerance to moisture compared to SrI 2 :Eu.

Photoluminescence of CsMI3:Eu2+ (M = Mg, Ca, and Sr) – a spectroscopic probe on structural distortions

“…Similar to CsCaI 3 , Eu 2+activated CsSrI 3 also shows efficient radioluminescence and is thus a promising candidate for scintillation materials. 20,21 Table 2 Positions of the 4f 6 ( 7 F J )5d 1 states in CsMgI 3 :0.1% Eu 2+ and energy differences DE J-0 of the 4f 6 ( 7 F J )5d 1 (J = 1-6) states relative to the 4f 6 ( 7 F 0 )5d 1 state 4f 6 ( 7 F J )5d 1 (t 2g ) 4 f 6 ( 7 F J )5d 1 (e g ) showing blue luminescence upon UV irradiation at room temperature.

“…10 Recently, the applicability of CsMI 3 (M = Ca, Sr) as scintillators has been investigated and presented by the group of Melcher. [18][19][20][21] Due to the higher covalence of Eu-I bonds compared to other halides, the 5d-4f emission is described to shift to lower energies and thus located in the blue or even bluish-green region. 10 Since the iodides described in this paper mainly contain heavy ions, their applicability as scintillating materials seems absolutely plausible, as the previously mentioned publications also nicely illustrate.…”
