- Auger-free luminescence characteristics of Rb<sub>1−</sub><i><sub>x</sub></i>Cs<i><sub>x</sub></i>CaCl<sub>3</sub>
抄録
<p>Fast scintillation materials based on ternary halide mixed crystals, Rb1−xCsxCaCl3 were synthesized. Broad luminescence bands were observed around 360 nm and can be ascribed to Auger-free Luminescence (AFL) for vacuum ultraviolet core-level excitation. Several luminescence bands for interband excitation were also observed. For X-ray excitation, the band that is ascribed to AFL could be clearly detected. The scintillation decay components due to the AFL had decay time constant of 0.8 ns for RbCaCl3 and 2.0 ns for Rb1−xCsxCaCl3 (x ≠ 0). CsCaCl3 had the largest light yield of the AFL component, exceeding 1200 photons/MeV, which was slightly lower than that of BaF2. The light yield of the AFL component increased linearly with Cs content.</p>
