Abstract
We have synthesized Eu-doped CsBr transparent ceramics by spark plasma sintering (SPS) and a single crystal by the vertical Bridgman-Stockbarger method. Subsequently, we have investigated their optical, scintillation and dosimeter properties. In scintillation, both the materials showed a broad emission peaking around 440Â nm, and the origin was due to 4f65d1-4f7 transitions of Eu2+. In the optically-stimulated luminescence (OSL) properties, OSL intensity of the ceramic sample was higher than those of the crystal sample. The dosimetric sensitivities were confirmed as low as 0.01Â mGy using TSL while 0.1Â mGy using OSL for both of the ceramic and single crystal samples.
