Abstract:
(EN) In the present invention, an alkali halide scintillator powder is obtained by adding an additive containing ions serving as the luminescent center to an alkali halide powder serving as the matrix (S14) and crushing the alkali halide powder and additive or applying a mechanical energy that delivers impact force, shear force, shearing stress, or frictional force for mixing (S15) in order to dope the alkali halide of the matrix with the ions serving as the luminescent center. As a result, an alkali halide-based scintillator powder can be produced in air at room temperature without complex condition control and without high-vacuum, high-temperature processes, and further, a large scintillator sheet can be created.
(FR) Selon la présente invention, une poudre de scintillateur à base d'halogénure alcalin est obtenue par ajout d'un additif contenant des ions servant de centre luminescent à une poudre d'halogénure alcalin servant de matrice (S14) et broyage de la poudre d'halogénure alcalin et d'additif ou application d'une énergie mécanique qui délivre une force d'impact, une force de cisaillement, une contrainte de cisaillement, ou une force de frottement pour mélanger (S15) afin de doper l'halogénure alcalin de la matrice avec les ions servant de centre luminescent. En conséquence, une poudre de scintillateur à base d'halogénure alcalin peut être produite à l'air à température ambiante sans contrôle de conditions complexes et sans procédés sous vide poussé, à haute température, et en outre, une grande feuille de scintillateur peut être créée.
(JA)  母体となるアルカリハライド粉末に発光中心となるイオンを含む添加物を添加し(S14)、アルカリハライド粉末及び添加物を粉砕させ、あるいは、混合させるために衝撃力、剪断力、ずり応力あるいは摩擦力を与える機械的エネルギーを与えて(S15)、母体のアルカリハライド中に発光中心となるイオンをドーピングしてアルカリハライド系シンチレータ粉末を得るので、複雑な条件制御を行うことなく、かつ、高真空下、高温下のプロセスをとることなく室温、大気中にてアルカリハライド系シンチレータ粉末を製造でき、さらに大型のシンチレータシートを作成できる。
