Synthesis, structural and spectroscopic properties of acentric triple molybdate Cs2NaBi(MoO4)3

Microwave sol–gel synthesis and upconversion photoluminescence properties of CaGd2(WO4)4:Er3+/Yb3+ phosphors with incommensurately modulated structure

“…The atomic vibration values were obtained using the modified random-element-isodisplacement model [63]. Previously, the optimized version of the model was tested for several compounds [64][65][66]. The model parameters obtained for CaGd 2 (WO 4 ) 4 are shown in Table 4.…”

Microwave sol-gel synthesis, microstructural and spectroscopic properties of scheelite-type ternary molybdate upconversion phosphor NaPbLa(MoO4)3:Er3+/Yb3+

“…35 The transparent sols were dried at 120°C in a dry oven for one week. The obtained black dried gels were ground, heat treated at 350°C for 6 h to evaporate ethylene glycol and other remained organic substances and annealed at 850°C for 16 h. As it was previously stated, this temperature range is highly appropriate for the calcination of molybdate compounds [3,6,[40][41][42]. After the annealing process, pink colored particles were obtained for the doped samples.…”

“…For the recent years, complex molybdate crystals have become of extensive interest due to their stable chemical properties, rich crystal chemistry and potential applications in such fields as laser systems, electrochemistry and photonics [1][2][3][4][5][6][7][8][9][10]. Complex molybdates are actively investigated as host materials for the creation of rare-earth doped phosphors appropriate for the use in lightemitting devices [1,2,[11][12][13][14][15].…”

New triple molybdate Rb2AgIn(MoO4)3: synthesis, framework crystal structure and ion-transport behaviour

“…A new structure type of Rb 2 AgIn(MoO 4 ) 3 continues the series of rhombohedral framework molybdate types with a % 9-10 Å and long c periods represented by such structures as Na 0.625 Zn 0.625 Sc 1.375 (MoO 4 ) 3 (Lazoryak & Efremov, 1987) of the NASICON type, Cs 7 Na 5 Yb 2 (MoO 4 ) 9 (Basovich et al, 2011), K 5 (Mg 0.5 Zr 1.5 )(MoO 4 ) 6 (Klevtsova et al, 1994), K 5 Pb 0.5 Hf 1.5 (MoO 4 ) 6 (Bazarov et al, 2005), Cs 2 NaBi(MoO 4 ) 3 (Savina et al, 2015) and Nd 2 Zr 3 (MoO 4 ) 9 (Klevtsova et al, 2000). In these structures, there are parallel trigonal columns (rods) of cation-oxygen coordination polyhedra linked with circumjacent MoO 4 tetrahedra where filled polyhedra shared faces with each other or with slightly twisted empty trigonal prisms ( Fig.…”
