Growth and Scintillation Properties of Two-Inch-Diameter SrI2(Eu) Single Crystals

Abstract: The sealed vertical Bridgman (VB) method is the main technique used to grow SrI2(Eu) crystals because SrI2(Eu) is very hygroscopic. In this study, we grew SrI2(Eu) single crystals with two-inch diameters and four-inch lengths using the VB method equipped with a removable chamber. The SrI2(Eu) single crystals were produced by the Liquinert process, which requires careful consideration of the crucible material and growth atmosphere. After a review of available materials, carbon crucibles were selected due to the… Show more

“…The radiation defects in Tl-doped scintillators were studied in [9][10][11]. Despite the fact that halide scintillators are emerging with greater efficiency than CsI, such as SrI 2 -Eu [12][13][14], LaBr 3 -Ce [15,16], BaBrI-Eu [17][18][19], and BaBrCl-Eu [20], it does not lose its position on the market and remains one of the most popular scintillators at present. This is due to its relatively low price, as well as low hygroscopicity [21].…”

“…The most popular impurities for doping CsI crystals are Tl [2,3], Na [4,5] and Eu 2+ [6][7][8].

“…In particular, the halide vertical Bridgman (H-VB) method is used for the high hygroscopicity of the raw materials. 14) Large-diameter single crystals up to 2 inches in diameter, such as Eu:SrI 2 , 15,16) were reported by the H-VB method. The growth conditions are being improved to prevent the degradation of optical properties caused by impurities, defects, and segregation of the crystalline luminescent center.…”
