We have investigated spectral-luminescent properties of CsI-Sr (5 mol. \ 0n the initial mixture) crystals at the temperature of 10 and 295 K in the 1.55-16 eV energy range. The nature of the luminescence bands of CsI-Sr crystals has been analyzed. The conclusion about the excitons localization near cation vacancy of $\rm{Sr}^{2+}-\rm{v}_c^-$ dipole and near unidentified impurity in the CsI matrix has been made.
