| dc.description.abstractEn | Different samples of a solid solution of glaserite-type structure with the general formula Na2Ba1−xSrxMg(PO4)2(0 ⩽ x ⩽ 1) were synthesized by the Pechini method and characterized by X-ray powder diffraction (XRD), 31P NMR spectroscopy and photoluminescence of europium doped compounds. The XRD patterns show that Na2Ba1−xSrxMg(PO4)2 system adopts the trigonal symmetry with the space group of PView the MathML source3¯m1 for 0 ⩽ x ⩽ 0.55 while from x = 0.6, it crystallizes in the monoclinic symmetry with the space group P21/a. The four resonances observed in the 31P NMR spectra for each composition of the system Na2Ba1−xSrxMg(PO4)2 (0 ⩽ x ⩽ 1) are interpreted on the basis of four configurations of statistical distribution (Ba2+/Sr2+) in the neighboring cationic sites of a PO4 tetrahedron. The photoluminescence of doped samples with divalent and trivalent europium was analyzed according to their compositions. | |
