Optical and scintillation characteristics of Tb-doped SrY 2 O 4 single crystals

The optical and X-and γ -ray induced scintillation characteristics of Tb-doped SrY 2 O 4 single crystals using the floating zone technique were evaluated. Under UV and X-rays, several lines in the range of 350 to 650 nm were observed in all the prepared crystals, which were attributed to the Tb 3+ i...

Description
Summary:The optical and X-and γ -ray induced scintillation characteristics of Tb-doped SrY 2 O 4 single crystals using the floating zone technique were evaluated. Under UV and X-rays, several lines in the range of 350 to 650 nm were observed in all the prepared crystals, which were attributed to the Tb 3+ ions. In the pulse area spectra of a 137 Cs γ -ray source, the full-energy absorption peak was confirmed using a 1.0% Tb-doped crystal, and the light yield was estimated to be 12,000 photons/MeV.
