Abstract
The polycrystalline sample of LiBaPO : Tb (LBPT) was successfully synthesized by solution combustion synthesis and studied for its luminescence characteristics. The thermoluminescence (TL) glow curve of LBPT material consists of two peaks at 204.54 and 251.21°C. The optimum concentration was 0.005 mol to obtain the higher TL intensity compared to commercial TLD-100 phosphor. The peak shape method was used to calculate kinetic parameter (activation energy and frequency factor). In CW-OSL mode its sensitivity for beta exposure was found to be 50% compared to commercially available α-AlO : C and 40% than LMP (BARC), and photoluminescence spectrum of LBPT shows green emission when excited with 225 nm UV source.
