Abstract
The present disclosure discloses a method for growing a crystal for detecting neutrons, gamma rays, and/or x rays. The method may include weighting reactants based on a molar ratio of the reactants according to a reaction equation (1-x-z)X2O3+SiO2+2xCeO2+zZ2O3→X2(1-x-z)Ce2xZ2zSiO5+x/2O2↑ or (1-x-y-z)X2O3+yY2O3+SiO2+2xCeO2+zZ2O3→X2(1-x-y-z)Y2yCe2xZ2zSiO5+x/2O2↑; placing the reactants on which a second preprocessing operation has been performed into a crystal growth device after an assembly processing operation is performed on at least one component of the crystal growth device; introducing a flowing gas into the crystal growth device after sealing the crystal growth device; and activating the crystal growth device to grow the crystal based on the Czochralski technique.
