Magnesium-calcium ion co-doped yttrium aluminum garnet ultrafast scintillation ceramic and preparation method thereof
The invention relates to a magnesium-calcium ion co-doped yttrium aluminum garnet ultrafast scintillation ceramic and a preparation method thereof. A solid-phase reaction method is adopted, a two-step sintering process is facilitated, the general formula of the prepared magnesium and calcium ion co-doped garnet ceramic is CexGd (3-x) Ga (5-y) AlyO12: mMgO: nCaF2, in the formula, x is 0.001-0.005, y is 2-3, m is 0.005-0.015, n is 0.005-0.015, and m equals n. The ceramic CexGd (3-x) Ga (5-y) AlyO12: mMgO: nCaF2 prepared by the method has the advantages of high light yield, ultrafast decay and the like, effectively reduces the problem of defect aggravation caused by double-ion co-doping, can be applied to the fields of ultrafast pulse radiation detection, TOP-PET and the like, is prepared by adopting the solid-phase reaction method, is simple in process and relatively low in cost, and can realize industrial production.
