Embodiment 1
[0037] The process of growing cerium-doped yttrium-lutetium silicate scintillation crystals in the molybdenum crucible of this embodiment comprises the following steps:
[0038] (a) Use the LYSO solid-phase reaction material prepared by stoichiometric ratio with 5% Y and 0.5% Ce, and put the solid-phase reaction material into the molybdenum crucible;
[0039] (b) Put the crucible in a vacuum furnace and evacuate until the pressure in the furnace is 10Pa;
[0040] (c) The furnace is filled with flowing Ar and H 2 Mix gas and maintain pressure at 20kPa, Ar and H 2 The volume ratio is 1:1;
[0041] (d) When the temperature in the furnace rises to about 1400°C, re-evacuate until the pressure in the furnace is 10Pa, and then fill the furnace with flowing Ar and H 2 Mix gas and maintain pressure at 20kPa, Ar and H 2 The volume ratio is 1:1;
[0042] (e) Continue to heat up in the furnace until the solid-phase reaction material melts, and grow crystals after reaching normal cond...
