Dibarium Magnesium Phosphate

Synthesis and X-ray Powder Diffraction Study of New Phosphates in the Cu3(PO4)2–Sr3(PO4)2 System: Sr1.9Cu4.1(PO4)4, Sr3Cu3(PO4)4, Sr2Cu(PO4)2, and Sr9.1Cu1.4(PO4)7

“…43) with the -Sr (PO ) structure type and the compound SrFe (PO ) crystallizing in a monoclinic system were found in the Fe (PO ) }Sr (PO ) system (13). Crystal structures of compounds M \V Cu V (XO ) (M"Ca, Sr, Ba; X"P, V, As) usually di!er from crystal structures of compounds (similar in stoichiomerty) with other transition metals or magnesium due to the Jahn}Teller distortion caused by copper cations, for example, BaCu (PO ) (14) and BaNi (PO ) (15), Ba Cu(PO ) (16) and Ba Mg(PO ) (17), BaCu (VO ) (18) and BaMn (VO ) (19), and BaCu (AsO ) (20) and BaNi (AsO ) (21). Copper-containing compounds are interesting because of their magnetic properties.…”

Dopant Site Environment and Spectrum Blue Shift of Yellow‐Emitting Solid Solution Phosphor Ba2−xSrxMg(PO4)2:Eu2+

“…The Ba1 is surrounded by eight O atoms forming a bicappedtrigonal prism and Ba2 coordinate with seven O atoms, giving a monocapped trigonal prism. 25 When Ba 2+ ions were substituted by Sr 2+ in a certain concentration, Sr 2+ may occupy preferential one type of Ba With the further increasing Sr 2+ content (x = 1.5) consecutively, a competitive secondary phase of (Sr 0.86 Mg 0.14 ) 3 (PO 4 ) 2 with JCPDS 47-1895 appeared. The diffraction patterns of the impurity phase (Sr 0.86 Mg 0.14 ) 3 (PO 4 ) 2 were presented in Fig.…”

Wet-chemical preparation of barium magnesium orthophosphate, Ba2Mg(PO4)2:Eu2+, nanorod phosphor with enhanced optical and photoluminescence properties

“…Barium magnesium orthophosphate, Ba 2 Mg(PO 4 ) 2 , one of the most efficient host materials for Eu 2+ activator, has a monoclinic crystal structure that is described by the P2 1 /n (Z=4) space group 27 . In its crystal lattice, two different Ba 2+ sites (7-and 8-coordinated) 28 .…”

“…According to the literature27 , BMP has monoclinic lattice symmetry that is described by the P2 1 /n space group.Mg and P interact with octahedral and tetrahedral O intersitices, thereby forming a MgO 6 octahedron and PO 4 tetrahedron, respectively.
