Abstract
Glass–ceramic nanocomposites comprising loaded sodium-aluminosilicate glasses in which scintillating crystallites are precipitated in situ from a host glass matrix were studied. This materials system shows promise as an alternative to single-crystal scintillators, with potential to be fabricated into a wide variety of sizes, shapes, and compositions. Batch compositions containing 15–18 mol. % and 3–4 mol. % were prepared and analyzed for photoluminescent light yield. Light yield peaked with rare-earth content of 15 mol. % and 4 mol. % . Preliminary ceramization studies on this composition found that the precipitated phase more closely matched a mixture rather than the that was targeted.
