Optical and scintillation properties of CsI:In crystals
The work is dedicated to study of optical and scintillation properties of CsI:In crystals. Using the Bridgeman method a concentration row of CsI:In single crystals was grown with the dopant content from 10⁻⁴ to 10⁻¹ mol. %. The segregation coefficient of In in CsI was estimated to be ~0.15. In...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The work is dedicated to study of optical and scintillation properties of CsI:In crystals. Using the Bridgeman method a concentration row of CsI:In single crystals was grown with the dopant content from 10⁻⁴ to 10⁻¹ mol. %. The segregation coefficient of In in CsI was estimated to be ~0.15. In CsI:In luminescence spectra one symmetric band is observed, peaking around 545 nm, with FWHM of 0.46 eV. Under intracenter excitation 1.9 μ s exponential decay was observed. The light yield under gamma excitation of ¹³⁷Cs isotope (662 keV), measured with a shaping time of 10 μ s, was 27 000 photons/MeV. The radio-luminescence yield of CsI:In , measured by the current mode method, approached to that of CsI:Tl . Probably, this difference is connected with the presence of a stronger afterglow in CsI:In crystals. |
