Sr2SiO4:%3Nd3+ was synthesized and its structural characterization made via XRD technique. The results indicated that had Pmma (62) space group (PDF: 00-039-1256) in the orthorhombic crystal system. Luminescence thermoluminescence (TL) properties of Sr2SiO4:%3Nd3 investigated detail. Computerized glow curve deconvolution methods used for to determine kinetic Sr2SiO4:%3Nd3+. TL showed Sr2SiO4:Nd...
