Scintillation Properties of and Self Absorption in ${\rm SrI}_{2}\!:\!{\rm Eu}^{2+}$

The scintillation properties of pure SrI2 and SrI2 doped with 0.5%, 0.86%, 2%, and 5% europium were studied. Different techniques were used to measure γ-ray excited pulse-height and scintillation decay time spectra, and to perform X-ray excited and optically excited emission spectroscopy. Eu2+ emission and trapped exciton (TE) emission was observed in SrI2:Eu2+ samples. These emissions were studie...
