Structural Refinement and Photoluminescence Properties of MnWO4 Nanorods Obtained by Microwave-Hydrothermal Synthesis

Cluster Coordination and Photoluminescence Properties of α-Ag2WO4 Microcrystals

“…Therefore, the main difference in PL spectra of α-Ag 2 WO 4 microcrystals can be attributed to the ratio between ordered [WO 6 ′ (y = 7, 6, 4, and 2) clusters in pairs have extrinsic defects, which are linked to order−disorder effects in the electronic structure, surfaces, and interfaces commonly verified in tungstate-type materials synthesized by chemical methods. 62,63 These defects create additional energy states above the valence band and below the conduction band, which decrease the band gap.…”

Effect of partial preferential orientation and distortions in octahedral clusters on the photoluminescence properties of FeWO4 nanocrystals

“…7,8 The second tungstate oxides exhibit a wolframite-type monoclinic structure where both M and W atoms are bonded to six oxygen atoms, which results in the formation of octahedral [MO 6 ]/[WO 6 ] clusters. 9,10 These differences in the coordination/structure cause defects in the crystal lattice and the appearance of photocatalytic, 11,12 photoluminescence (PL), [13][14][15][16] humidity sensor [17][18][19] and magnetic properties 20,21 as well as electronic properties for the tungstates.…”

Sonochemical Synthesis and Characterization of the New Micro-Hexagonal-Rod Lead (II)-Azido Coordination Compound

“…The acceptable match with very slight differences in peak positions indicates that both materials have a single crystalline phase. A comparison of the theoretical and experimental XRD pattern data may be investigated using the Rietveld refinement [41]. Micro hexagon-rods that are prepared sonochemically have been observed by SEM (Fig.…”
