Hydrothermal synthesis, structure, and property characterization of rare earth silicate compounds: NaBa3Ln3Si6O20 (Ln = Y, Nd, Sm, Eu, Gd)

“…[1][2][3][4] Additionally, lanthanide silicates exhibit high thermal stability, ion exchange properties, and rich structural chemistry owing to great number of possible different coordination environments in lanthanide elements. 5 Crystal growth of these silicates can typically be achieved via hydrothermal [6][7][8][9][10] and flux [11][12][13][14][15] growth techniques. The chemistry of lanthanide-based silicates has been summarized by Wickleder in 2002, 16 and that work identifies several mixed alkali-alkaline earth-rare earth silicates reported in the literature.…”

“…G j → 7 F 0 9,10. The emission spectrum was recorded using 532 nm excitation ( 5 D 1 ← 7 F 0 ) and exhibits several emission bands between 550−750 nm.…”

Synthesis and magnetic property of submicron Bi2Fe4O9

“…Hydrothermal route has been extensively used in recent years due to easy control of chemical homogeneity, purity, morphology, shape, and phase composition of the products under moderate conditions [5,6]. Many important functional materials have been successfully prepared by hydrothermal route, such as microporous crystals, superionic conductors, chemical sensors, electronically conducting solids, complex oxide ceramics and fluorides, magnetic materials, and luminescence phosphors [7][8][9][10][11][12][13][14][15]. Basically, the mechanism of hydrothermal reactions abides by a liquid nucleation model [16].…”

(3+1)-Incommensurately modulated crystal structure of Cs3ScSi6O15

“…On the other hand, quite a number of caesium-bearing synthetic oxosilicates containing trivalent rare earth element (REE) cations that can be potentially used as host lattices for luminescence have been disclosed in the literature. Examples include Cs 3 NdSi 8 O 19 and CsNd 2 Si 21 O 48 (Schä fer & Schleid, 2009), Cs 3 EuSi 6 O 15 (Huang et al, 2005), Cs 3 DySi 6 O 15 ( (Kolitsch et al, 2009) as well as Cs 3 ScSi 8 O 19 (Kolitsch & Tillmanns, 2004).…”
