Structural, Optical & Thermal Properties of a Host Crystal Lattice and to Explore its Inherent Possibilities

<p>Host Ba2MgSi2O7 phosphor was successfully prepared via low temperature combustion synthesis<br>route. The phase identification of the prepared phosphor was done with the help of powder XRD<br>technique. The XRD pattern of the phosphor revealed its monoclinic crystal symmetry with a space<br>group C2/c. XRD pattern of synthesized powder sample have well-matched with the help of JCPDS<br>PDF Card No. #23-0842. The average crystallite size calculated as 44nm with the help of Debye<br>Scherer’s mathematical formula and also calculated as 56nm using Williamson–Hall (W–H) plot<br>method and crystal lattice strain has been calculated as 0.24nm. This Raman line corresponds to the<br>stretching vibrations of the Si–O bonds of the Si2O7 group. It is acquired that the sample exposed for<br>15min gives optimum TL intensity at 112.190C temperature and displays single TL glow peak. On the<br>basis of TL glow curve, it can be suggested that the Ba2MgSi2O7 (BMS) phosphor is an efficient host<br>lattice but not a better TL phosphor. In thermo-luminescence property, the effect of 15min UV<br>exposure on different kinetic parameters for this peak was determined with the help of peak shape<br>method. In our present study, we have studied on the XRD, FESEM, Raman & IR Spectra and thermoluminescence (TL) characteristics of this phosphor. </p>
