dc.description.abstractWe report that terbium doped lithium borate phosphors were synthesized by conventional solid state reaction method for the first time. X-ray diffraction (XRD) analysis, radioluminescence (RL) and thermally stimulated luminescence (TSL) were used to investigate structural and luminescence properties of terbium doped lithium borate phosphors. XRD patterns confirm that the lithium borate phosphors sintered at 1200 degrees C exhibit monoclinic structure. RL spectrum revealed that terbium ions are present in trivalent oxidation states. RL measurements shows that the series of emission state D-5(4) -> F-7(6), D-5(4) -> F-7(5), D-5(4) -> F-7(4) and D-5(4) -> F-7(3), corresponding to the typical 4f -> 4f infra-configuration forbidden transitions of Tb3+, are appeared and major emission peak is around at 541 nm. The TSL kinetic parameters of a newly prepared terbium doped lithium borate phosphor have been calculated. The LiBO2:Tb3+ exhibits two TSL glow curves at around 90 and 155 degrees C. The kinetic parameters, namely activation energy (trap depth) and frequency factor (s) associated with the main glow peak (155 degrees C) of the material were determined using peak shape (PS) and various heating rates (VHR) methods.
