Abstract
Here, we have discussed that the thermal characteristics of well fascinated Ba2 MgSi2 O7: Eu2+, Dy3+ nano phosphor via combustion synthesis technique (CST) at the already well-maintained muffle furnace temperature at 6500C for 5min, and post annealed at 10000C for 2hours. Synthesized powder sample was further analysed for thermal properties with using Nucleonix (Hyderabad, India) Pc based TLD Reader (TL 1009I) with obtained thermoluminescence (TL) glow peak curves were plotted at room temperature. It has been identified that it contains a single prominent peak at 100.12°C temperature from TL glow curve. All the kinetic or trapping parameters such as activation energy [E], order of kinetics [b], and frequency factor [S] of trap centre of the fitted thermoluminescence (TL) glow curves of the synthesized powder samples were examined at different UV exposure times via Chen’s empirical formula. The position of the TL peak shifts towards optimum temperature, indicating the considerable retrapping associated with general order kinetics (b). The depths of the trap were found to between in the range of 0.62 to 0.76eV. The prepared phosphor shows potential application as per long persisting behaviour. We have proposed that the combined phosphor is a more efficient thermoluminescent material.
