More Information
Summary:To provide a scintillator material which has superior moisture resistance and is capable of emitting visible light well in the presence of radiation, and to provide a radiation detection device and a method of manufacturing the scintillator material.SOLUTION: A scintillator material that emits visible light when excited by radiation is provided. The scintillator material has a cristobalite structure with partially crystallized silica. SrI2:Eu2+, a phosphor material, is entrapped in the cristobalite structure to form a nanocomposite. The cristobalite structure contains an alkali metal ion.SELECTED DRAWING: Figure 1 【課題】耐湿性に優れ、放射線によって良好に可視光を発光するシンチレータ材、放射線検出装置およびシンチレータ材の製造方法を提供する。【解決手段】放射線により励起されて可視光を発光するシンチレータ材であって、シリカの一部が結晶化したクリストバライト構造を有し、蛍光体材料であるＳｒＩ２：Ｅｕ２＋がクリストバライト構造中に取り込まれてナノコンポジット化しており、クリストバライト構造にアルカリ金属イオンを含むシンチレータ材。【選択図】図１
