Inorganic compositions were prepared by melt spinning. An inorganic melt was sent to a spinning wheel. As the melt contacts the wheel, it cools and is converted into a solid composition. A melt prepared from lanthanum halide powder and cerium halide powder was converted to a scintillator product of nanoparticles embedded in a glassy matrix.
