摘要: Rare-earth-doped phosphors are drawing attention due to their applications in various fields including medical imaging. Lithium lutetium borate has very good absorption efficiency comparison other phosphors. The presence of Lu with its high effective atomic number (Zeff = 52) and molecular weight (M.Wt 393 g/mol) make lithium a potential detector for X-ray On the hand, 6Li (lithium) 10B (boron) may Li6Lu(BO3)3 as promising neutron detector. For this work Li6Lu(BO3)3:Ce3+, Li6Lu(BO3)3:Pr3+ Li6Lu(BO3)3:Tm3+ were synthesized by using solid-state reaction method. crystallinity particle morphology characterized XRD (X-ray diffraction) FE-SEM (field-emission scanning electron microscopy). Luminescence properties such X-ray-induced luminescence, proton-induced luminescence UV photoluminescence measured
