Lanthanide Organic–Inorganic Hybrids for X‑ray Scintillation and Imaging

Two X-ray scintillators based on organic–inorganic hybrids were constructed by judiciously incorporating lanthanide cations and organic ligands within a single material. The obtained Eu-pba and Tb-pba not only feature excellent radiation, hydrolytic, and thermal stabilities but also exhibit a linear...

Description
Summary:Two X-ray scintillators based on organic–inorganic hybrids were constructed by judiciously incorporating lanthanide cations and organic ligands within a single material. The obtained Eu-pba and Tb-pba not only feature excellent radiation, hydrolytic, and thermal stabilities but also exhibit a linear response to the X-ray dose rate with detection limits of 4.92 and 3.17 μGy s–1, respectively. We further present a flexible scintillator film fabricated by embedding Tb-pba in a polydimethylsiloxane (PDMS) polymer. Their incorporation enables X-ray imaging with a spatial resolution of approximately 10 lp mm–1. These results emphasize the potential of lanthanide organic–inorganic hybrids to achieve outstanding performance in X-ray scintillation and imaging.
