Americium doping induced self irradiation of SrBPO5: 241Am: Spectroscopic insight
In the present work, 241Am incorporated in SrBPO5 (SBP) host matrix was investigated by various spectroscopic techniques to understand the trap level spectroscopic properties of the system. Photoluminescence (PL) depicted stabilization of Am in +3 oxidation state with low local symmetry. Thermoluminescence (TL) on the other hand suggested that creation of self irradiated defects in SBP:241Am leads to a glow curve around 463 K. Electron spin resonance (ESR) further confirmed the creation of borate radical in axial symmetry on doping ‘Am’ in SBP with hyperfine splitting. We could further propose the mechanism of TL glow curve on doping Am in the SBP lattice.
