Fabrication of Gd2O2S:Tb scintillation ceramics from the uniformly doped nanopowder

Enhanced X-ray Imaging with Gd2O2S:Pr-Epoxy Composite Films: Synthesis, High-Resolution Performance, and Flexibility

“…Scintillation materials, which emit light when excited by high-energy particles, are available in various forms, including organic, − inorganic, − and organic–inorganic composite scintillators. , Organic scintillators offer quick response and flexibility but suffer from lower efficiency and radiation resistance. − In contrast, inorganic scintillators deliver higher efficiency and durability but at a higher cost and with fabrication limitations. − Organic–inorganic composite scintillators, combining organic substances with inorganic scintillation components, offer a promising solution by merging the benefits of both types, such as cost-effectiveness and tunable scintillation properties . These advantages of organic–inorganic composite scintillators make them suitable for practical applications in X-ray panel imaging.…”

Study on luminescence properties of Gd2O2S: Tb3+ phosphors with different excitation sources

“…It is found that Tb 3+ ion concentration not only affects the luminous intensity of Gd 2 O 2 S: Tb 3+ phosphor, but also affects the emission intensity ratio of blue/green light [8] . In rare earth phosphors, the optimal activator concentration also varies with the excitation type [9][10][11] . In addition, Li Gen et al [12] found in the study of NaBaScSi 2 O 7 : Tb 3+ phosphor that when the excitation source changes from ultraviolet excitation to cathode ray excitation, the optimal doping concentration of Tb 3+ also changes, but the relevant research in Gd 2 O 2 S: Tb 3+ phosphor has not been reported.…”
