Abstract
This paper reports on the preparation and growth of Eu-doped strontium iodide ( ${\rm SrI}_{2}$ ) single crystals by modified micro-pulling-down method. Influence of the ${\rm Eu}^{2 + }$ and ${\rm Eu}^{3 + }$ (introduced in form of ${\rm EuI}_{2}$ and ${\rm EuCl}_{3}$ ) on the luminescence and scintillation properties is analyzed. Sufficient optical quality of prepared single crystals was obtained allowing further characterization of their absorption, radio- and photoluminescence spectra. Photoluminescence and scintillation decay time of grown ${\rm SrI}_{2}$ crystals irradiated under $\gamma $ -ray source were evaluated as well.
