Growth of 1.5-In Eu : SrI2 Single Crystal and Scintillation Properties.

We grew 1.5-in Eu doped SrI2 (Eu:SrI2) bulk single crystal by a modified vertical Bridgman (VB) method using a removable chamber and high-frequency induction heating. As-grown 1.5-in Eu:SrI2 bulk single crystal had no visible crack and inclusion in the crystal. In the transmittance and $\alpha $-ray radioluminescence spectra, large absorption below 433 nm and emission peak at 433 nm were observed, respectively. Each polished 56 \thinspace 000 \sim 62 \thinspace 000\ \ph/MeV light yield and 3.3 \sim 3.9\%$ energy resolution. The decay times of the specimens were 0.61 \sim 0.67\ \mu \s. [ABSTRACT FROM AUTHOR]
