Scintillation ceramic, high-energy detection array, detector and preparation method
The invention provides scintillation ceramic, a high-energy detection array, a detector and a preparation method. The chemical formula of the scintillation ceramic is Gd3Al2-x-yScxGa3O12: yCr < 3 + >. The preparation method comprises the following steps: S01, dissolving Gd2O3, Sc2O3, Ga2O3, NH4Al (SO4) 2.12 H2O and Cr (NO3) 3 in a hot acid solution, dropwise adding the acid solution into an alkali solution for coprecipitation, collecting a precipitate, and washing the precipitate; s02, drying and grinding the precipitate to obtain powder; s03, the powder is pre-sintered; s04, performing grinding, sieving, dry pressing and cold isostatic pressing treatment on the pre-sintered powder; and S05, carrying out primary sintering in an oxygen atmosphere, and carrying out isostatic pressing sintering in an inert atmosphere to obtain the compact ceramic. The garnet scintillation ceramic provided by the invention can realize high absorption intensity and luminous intensity of broadband, and shows good luminous performance and detection efficiency.
本发明提供一种闪烁陶瓷、高能探测阵列、探测器及制备方法，所述闪烁陶瓷化学式为Gd3Al2‑x‑yScxGa3O12:yCr3+。制备方法包括：S01，将Gd2O3、Sc2O3、Ga2O3、NH4Al(SO4)2·12H2O和Cr(NO3)3溶于热酸溶液中，将酸溶液滴入碱溶液中进行共沉淀，收集沉淀物并洗涤；S02，将沉淀物干燥、研磨，得到粉体；S03，将粉体预烧；S04，将预烧后的粉体研磨、过筛、干压和冷等静压处理；S05，在氧气气氛中进行一次烧结，在惰性气氛中进行等静压烧结成致密陶瓷。本发明的石榴石闪烁陶瓷可以实现宽波段的高吸收强度和发光强度，表现出良好的发光性能和探测效率。
