Structure, electronic properties, morphology evolution, and photocatalytic activity in PbMoO₄ and Pb_1−2xCa_xSr_xMoO₄ (x = 0.1, 0.2, 0.3, 0.4 and 0.5) solid solutions

Abstract

In this work PbMoO4 and Pb1-2xCaxSrxMoO4 (x= 0.1, 0.2, 0.3, 0.4 and 0.5) solid solutions have been successfully prepared, for the first time, by a simple co precipitation method and...

Bridging experiment and theory: Morphology, optical, electronic, and magnetic properties of MnWO4

“…This procedure has been performed to obtain the complete set of morphologies of different materials based on the Wulff construction and the values of E surf and to investigate the magnetic and multiferroic properties of different materials [19,37,[41][42][43][44][45][46][47][48], in addition to pathways connecting the different morphologies. The energy (E pol ) and band gap energy (E poly gap ) of the polyhedron were calculated by assuming the contributions from each surface to the morphology (C (hkl) i…”

A Chemical-Pressure-Induced Phase Transition Controlled by Lone Electron Pair Activity

“…Solid solutions of semiconductors are pertinent examples to illustrate how the interactions associated with the doping process mimic the effect of thermodynamic variables (pressure and temperature) and also modulate the properties of advanced materials with extended functionalities (see for example refs , ). Among these solid solutions, the ternary metal tungstate- and molybdate-based compounds form an important class of multifunctional materials with a combination of covalent, ionic, and metallic bonding that has been widely studied due to their fundamental and industrial interest. − In spite of being in the next period, tungsten shows a similar atomic radius as molybdenum due to the well-known lanthanide contraction. This good size matching guarantees the alloying of the two semiconductors in a wide composition range and avoids the phase separation that otherwise would occur originated by large lattice-mismatching strains.…”
