1. A method, comprising:

  • placing into a crucible precursors including;

    a rare earth halide precursor; and

    a dopant precursor that includes a strontium halide, a barium halide, or any combination thereof;

    melting the precursors;

    forming a scintillation crystal comprising Ln(1-y)REyX3;

    Me2+, wherein;

    Ln represents a rare earth element;

    RE represents a different rare earth element;

    y has a value in a range of 0 to 1;

    X represents a halogen; and

    Me2+ represents Sr, Ba, or any mixture thereof and has a concentration of at least 0.0002 wt. %; and

    roughening a surface of the scintillation crystal.
