Abstract
In recent decades, storage phosphors have found widespread applications in the fields of dosimetry and computed radiography due to their impressive properties including large dynamic range and passive storage mode. Despite this success, further development of highly efficient X-ray and UV sensitive luminescent materials is still desirable, in par-ticular for applications in dosimetry. In this Article we report X-ray and UV storage properties of nanocrystalline Ba-LiF3 doped with Sm3+. Nanocrystalline BaLiF3:Sm3+ was prepared mechanochemically by ball milling and the resulting product was characterized by powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). The re-sponse of the phosphor to X-ray and UV radiation was investigated by measuring room temperature photolumines-cence spectra before and after irradiation for a wide range of doses. The lifetime of the Sm2+ emission at 694 nm was determined for both the X-ray and UV irradiated powder samples. The results indicate a potential fo...
