Abstract

Optical, scintillation and dosimeter properties of Mn 0.3 and 10 mol% doped LiCaAlF6 and Mn 10 % doped LiCaAl0.9Ga0.1F6 crystals were studied. Mn2+ emission appeared around 520 nm in the photoluminescence, scintillation and optically stimulated luminescence (OSL). As a dosimeter, the OSL and thermally stimulated luminescence (TSL) dose response functions were evaluated, and both the OSL and TSL showed a good linearity between the irradiated X-ray dose and response signal intensity from 1 to 1000 mGy. Compared with previously reported Ce- or Eu-doped LiCaAlF6, OSL properties were improved.
