Crystal Structures and Magnetic Properties of Rare-Earth Ultraphosphates, RP5O14 (R=La, Nd, Sm, Eu, Gd)

Magnetic and Photon Cascade Emission of Gd3+ of NaGd(PO3)4 Monocrystal Under Appropriate Synthesis Conditions

“…[25]. When the theoretical effective moment was compared to the experimental one, we can see that the theoretical value are more important than those obtained experimentally.…”

A Series of Lithium Rare Earth Polyphosphates [LiLn(PO3)4] (Ln = La, Eu, Gd) and Their Structural, Optical, and Electronic Properties

“…For example, Yamada et al have reported the use of [LiNd(PO 3 ) 4 ] [12,13] as a solid-state laser material whose relatively large Nd-Nd distance gives rise to a lesser degree of fluorescence quenching. Parreu 4 ] (Ln = Nd, Gd) crystals [14,15] and explored their second harmonic generation, and Naili et al have reported the crystal structures of [MGd(PO 3 ) 4 ] (M = K, Cs). [16,17] Recently, [NaLa(PO 3 ) 4 ] [18] was synthesized in our laboratory.…”

“…Furthermore, their chemical and thermal stability ensures their utility in industrial applications. The common basic structural unit of these materials is the PO 4 group, and the varied condensations of PO 4 groups result in several structural families, [7][8][9][10] one of which is polyphosphates with the general formula [MLn(PO 3 ) 4 ] (M = alkali metal, Ln = rare earth metal). [11] Some polyphosphates with interesting optical properties have been reported in this family.…”

“…Rare earth phosphate materials have been extensively investigated due to their structural diversity [1][2][3] and potential properties (magnetism, [4] electricity, [5] and optics [6] ). Furthermore, their chemical and thermal stability ensures their utility in industrial applications.…”

Synthesis and Crystal Structure of LiLaP4O12

“…2) 9,10 Each La polyhedron is connected by means of common corners and by common faces with Na or Ag polyhedral. The LaO8 dodecahedron shares all of its oxygen atoms with the corners of the neighboring PO4 tetrahedral, and with the faces of the neighboring Li polyhedral.…”
