Abstract

Li₆Lu(BO₃)₃Eu³⁺ and Li ₆Lu(BO₃)₃Sm³⁺ are produced by solid state reaction. We have synthesized and characterized the luminescence of their properties for the first time. Firstly, we confirmed the structure and shape of Li₆Lu(BO₃)₃Eu³⁺, ³⁺ phosphor using X-ray diffraction. Secondly, we optimized doping concentrations of activators. The lithium lutetium borate has a high effective atomic number(Z_eff=52) and the molecular weight is 393 g/mol. Hence, it is considered that the efficiency of absorption is high in comparison to that of commonly used phosphor in X-ray imaging. Additionally, Li₆Lu(BO ₃)₃Eu³⁺ and Li₆Lu(BO ₃)₃Sm³⁺ emit a luminescence of the red region that are well matched with CCDs in terms of quantum efficiency. Furthermore, host material involves a large amount of lithium and boron. The neutron interacts with these materials. Consequently Eu³⁺ or Sm³⁺ doped Li₆Lu(BO₃)₃ phosphor can be a good candidate not only for X-ray imaging in medical fields but also for neutron detection imaging in various industrial fields.
