The results of studies for the optical transmission spectra, radiation
hardness and the refractive indices of Ba(1-x)SrB2O4 (x=0.1) single crystals
grown with the Czochralsky technique are presented. The investigations
have shown that the substitutive Sr impurity improves the technological
process of single-crystal growth, though leads simultaneously to worsening
the transmittance and the radiation hardness. The assumption about the
additional influence of incontrollable Na impurity on the mentioned properties
of Ba0.9Sr0.1B24 single crystals is made.
Key words: alpha-BaB2O4 single crystals, impurities, transmission
spectra, radiation hardness, refractive index
