Abstract
An afterglow property of cesium iodide:thallium (CsI:Tl), in which CsI is a host material and doped with thallium, is improved. It is possible to improve the afterglow property of a scintillator by doping a crystal material including CsI (cesium iodide), as a host material, and thallium (Tl), as a luminescent center, with bismuth (Bi).
Claims10
A scintillator comprising a crystal material including CsI (cesium iodide), as a host material, and thallium (Tl), as a luminescent center, and doped with bismuth (Bi).
A scintillator obtained through crystal growth after mixing a raw material including a CsI raw material, a Tl raw material, and a Bi raw material, and melting the raw material by heating.
A method of reducing an afterglow of a scintillator comprising:
- melting a raw material including a CsI (cesium iodide) raw material, a thallium (Tl) raw material, and a bismuth (Bi) raw material;
- and
- growing a crystal from the melted material.
