| titleOfInvention | Double doped scintillation crystal manufacturing method |
| abstract | A method for preparing a double-doped scintillation crystal by using a Czochralski (Cz) method to grow a double-doped yttrium and a calcium or a magnesium element rare earth lanthanide single crystal rod, which is produced by doping calcium or magnesium Charge Compensation, which causes the charge compensation of calcium or magnesium and yttrium tetravalent (Ce+4) to produce yttrium trivalent (Ce+3) to form a calcium lanthanide double doped rare earth strontium single crystal. a rod or a magnesium-doped double-doped rare earth silicate single crystal rod, which is then placed in a high temperature apparatus for thermal annealing treatment, the calcium lanthanum double doped rare earth silicate single crystal rod or the magnesium lanthanum The double-doped rare earth strontium single crystal rod is heated from room temperature to between 1400 and 1600 ° C, and then subjected to a temperature-reaction time, followed by a temperature-lowering step. Thereby, the present invention performs thermal annealing treatment under the atmosphere, and the thermal annealing can greatly reduce the fragmentation of the crystal during processing, and can improve the yield of the pixel sample after the crystal cutting and polishing, and has the process cost. Low, high yield, less crystal fragmentation, high light intensity and short decay time. |
