1. from having general formula Ln 2xA 2yLu 2 (1-x-y)SiO 5The melt of composition in the method for growing single-crystal scintillator material;

  • Wherein Ln is basically by one or more lanthanon, one or more actinoids or combinations thereof;

    A is made up of one or more IIA in the periodic table of elements or IIB family element or its any combination basically, and said method comprises;

    Select the end points that comprises of the monocrystal material institute desire acquisition of growth to arrive the fluorescence decay time between about 50ns at interior about 30ns;

    Based on the fall time that desire obtains, confirm the relative value between x and the y, wherein x is more than or equal to 0.00001 and be less than or equal to 0.1, and y is more than or equal to 0.00001 and be less than or equal to 0.1 so that from melt, obtain the stable growth of single crystal scintillator material;

    WithGrowing single-crystal scintillator material from melt with the said relative value between x and the y.
