Glass scintillator: A window to future high-energy radiation detection.

With the significant progress of high-energy physics, nuclear science, and technology, the demand for high-performance scintillators is growing rapidly. Among solid-state scintillators, glass scintillators would play a vital role in the field of high-energy radiation detections because of their merits including low cost, batch production, and arbitrariness in shape. In this review article, the research and development of glass scintillators is introduced with respect to the following key parameters including: density, light yield, scintillation decay time, and radiation hardness.

Band Gap and Defect Engineering Enhanced Scintillation from Ce-Doped Nanoglass Containing Mixed-Type Fluoride Nanocrystals.

Much can be learned from the research and development of scintillator crystals for improving the scintillation performance of glasses. Relying on the concept of "embedding crystalline order in glass", we have demonstrated that the scintillation properties of Ce-doped nanoglass composites (nano-GCs) can be optimized via the synergistic effects of Gd-sublattice sensitization and band-gap engineering. The nano-GCs host a large volume fraction of KYGdF mixed-type fluoride nanocrystals (NCs) and still retain reasonably good transparency at Ce-emitting wavelengths.

Highly stable CsPbBr perovskite quantum dot-doped tellurite glass nanocomposite scintillator.

All-inorganic cesium lead halide perovskite quantum dots (PQDs) appear to be promising scintillators for radiation detection; however, they are suffering from poor stabilities against light, heat, and moisture. Here a strategy of using AgCl as the nucleating agent is developed to facilitate growth of PQDs in chemically inert tellurite glasses via controlled crystallization. The PQDs are uniformly dispersed and well protected in the dense glass matrix without aggregation.
