Bright Transparent Scintillators with High Fraction BaCl₂ : Eu²⁺ Nanocrystals Precipitation: An Ionic-Covalent Hybrid Network Strategy toward Superior X-Ray Imaging Glass-Ceramics.

ABSTRACT: Metal halide crystals are bright but hygroscopic scintillator materials that are widely used in X-ray imaging and detectors. Precipitating them in situ in glass to form glass ceramics (GCs) scintillator offers an efficient avenue for large-scale preparation, high spatial resolution, and excellent stability. However, precipitating a high fraction of metal halide nanocrystals in glass to maintain high light yield remains a challenge. Herein, an ionic-covalent hybrid network strategy for constructing GCs scintillator with high crystallinity (up to ≈37%) of BaCl₂ : Eu²⁺ nanocrystals is presented. Experimental data and simulations of glass structure reveal that the Ba²⁺ -Cl^- clustering promotes the high crystallization of BaCl₂ nanocrystals
