Transparent Microcomposite Films Based on a Ce-Doped Li₆Gd(BO₃)₃ Scintillator for Radiation Detection.

ABSTRACT: Scintillators are widely used for high-energy radiation detection. Hybrid inorganic-organic composite scintillators with high light yields, high light decay rates, excellent stability, and low costs are in great demand. Here, we report a novel scintillator composed of Ce-doped Li₆Gd(BO₃)₃ (LGBO) microphosphors (MPs) and polymethyl methacrylate for X-ray and thermal neutron detection. The Ce-doped LGBO MPs, fabricated using a facile high-temperature solid-state reaction method, exhibit intense blue light at 416 nm under X-ray and UV excitation and have a high photoluminescence quantum yield of ∼63%. More importantly, the composite scintillator based on these MPs has excellent transparency and luminescence intensity. The luminescence integral intensity of com
