ABSTRACT:
A method of making a rare earth halide single crystal material is provided. The method includes providing a polycrystalline material having a plurality of grains. The method further includes adding a seed crystal to the polycrystalline material to define a plane of growth for the polycrystalline material. Further, the polycrystalline material having the seed crystal may be subjected to heat-treating, where the heat-treating does not include melting the polycrystalline material.
