Structural and Thermal Properties of a Selected Host Crystal Lattice: Exploration of Inherent Possibilities
Keywords:X-ray Diffraction Pattern (XRD), Ba2MgSi2O7 (BMS), Monoclinic, C2/c, Combustion Synthesis.
Host Ba2MgSi2O7 phosphor was successfully prepared via low temperature combustion synthesis route. The phase identification of the prepared phosphor was done with the help of powder XRD technique. The XRD pattern of the phosphor revealed its monoclinic crystal symmetry with a space group C2/c. The XRD pattern have well clarified with JCPDS PDF card no. #23-0842. The average crystallite size was calculated as 42nm and crystal lattice strain size calculated as 0.24, respectively. It is acquired that the sample UV exposed for 15min gives optimum TL intensity at 112.190C temperature and displays single TL glow peak. On the basis of TL glow curve, it can be suggested that the Ba2MgSi2O7 (BMS) phosphor is an efficient host lattice but not a better TL phosphor. In our present study, we have discussed on the XRD, FESEM and thermo-luminescence (TL) characteristics as well as different kinetic parameters of this phosphor.
