Abstract
Ba2MgSi2O7:Dy3+ (BMSD) white light emitting phosphor was sintered by combustion synthesis route. The phase formation was confirmed with the help of XRD characterization. The results of the XRD study obtained for this phosphor revealed its monoclinic crystal symmetry with a space group C2/c. The XRD pattern well matched with the help of JCPDS Pdf file No. 23-0842. The average crystallite size was calculated as 31.63nm and strain as 0.27. Functional group investigation with the help of FTIR spectroscopy and Photoluminescence properties were also discussed. The sintered Ba2MgSi2O7:Dy3+ (BMSD) phosphor was stimulated at 383nm and their corresponding emission spectra were peaked at blue (477 nm), yellow (574 nm) and red (677nm), three spectral lines because of the 4F9/2→6H15/2, 4F9/2→6H13/2, 4F9/2→6H11/2, transitions of trivalent dysprosium [Dy3+] ions. In this paper, the XRD, FTIR and photoluminescence properties of this phosphor are also investigated in detail.
