Abstract
By using a chemical combustion synthesis (CCS) approach, an akermanitestructured (Ca2MgSi2O7) composite nanophosphor with varying amounts of doped Eu2+ and co-doped Dy3+ ions were successfully synthesized. In this present investigation, the structural, morphological, elemental composition, and thermal characteristics have been studied as an outcome of XRD, FESEM, EDX, and TL characterizations. XRD patterns have shown that the as-synthesized powder samples have single-phase tetragonal crystal structure. Thermoluminescence (TL) properties have been evaluated, including with kinetic or trapping parameters. At 110.78 °C, single TL glow curve peak of the synthesized sample UV exposed for 15 min gives optimum intensity. In this sequence, it was confirmed that the doping concentration effect of rare earth ions is more responsible for the enhancement of TL intensity. The extensive variety of TL materials discovered so far and their different physical appearances allow the determination of different radiation features. Based on the result of TL characteristics and evaluated trapping parameters, it was found that as-synthesized nano-sized material is an excellent TL material that exhibits long persistent property. TL materials with deeper traps can be used in high temperature radiation dosimetry applications. In this sequence, the present article describes the significant roles of dopant and co-dopant rare earth ions in enhancing the long persistent properties of as-synthesized nano-sized Ca2MgSi2O7: Eu2+, Dy3+ phosphor.
