Compression of scheelite-type SrMoO4 under quasi-hydrostatic conditions: Redefining the high-pressure structural sequence
American Institute of Physics (2013)The high-pressure behavior of tetragonal SrMoO4 was analyzed by Raman and optical-absorption measurements. Pressures up to 46.1 GPa were generated using diamond-anvil cells and Ne or N2 as quasi-hydrostatic pressure-transmitting ... -
[Cr(dmbipy)(ox)2]−: a new bis-oxalato building block for metal assembling. Crystal structures and magnetic properties of XPh4[Cr(dmbipy)(ox)2]·5H2O (X = P and As), {Ba(H2O)2[Cr(dmbipy)(ox)2]2}n·17/2nH2O and {Ag(H2O)[Cr(dmbipy)(ox)2]}n·3nH2O
Royal Society of Chemistry (2010)The synthesis, X-ray structure and variable-temperature magnetic study of new compounds of formula PPh4 [Cr(dmbipy)(ox)2 ]$5H2O (1), AsPh4 [Cr(dmbipy)(ox)2 ]$5H2O (2), {Ba(H2O)2[Cr(dmbipy)(ox)2]2}n$17/2nH2O (3) and ... -
Piezoelectric Control of the Exciton Wave Function in Colloidal CdSe/CdS Nanocrystals
American Chemical Society (2016-05-25)Using multiband k·p calculations, we show that strain-engineered piezoelectricity is a powerful tool to modulate the electron−hole spatial separation in a wide class of wurtzite CdSe/CdS nanocrystals. The inherent ... -
Quantum mechanical modeling of excited electronic states and their relationship to cathodoluminescence of BaZrO3
American Institute of Physics (AIP Publishing LLC) (2013)First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** ... -
Structural refinement, growth mechanism, infrared/Raman spectroscopies and photoluminescence properties of PbMoO4 crystals
Elsevier (2013)Lead molybdate (PbMoO4) crystals were synthesized by the co-precipitation method at room temperature and then processed in a conventional hydrothermal (CH) system at low temperature (70 °C for different times). These ... -
Synthesis and structure of methoxo-terminated molybdenum and tungsten M3S4 clusters containing aminophosphine ligands
Elsevier (2019)Trinuclear [M3S4(OCH3)3](edpp)3] + complexes, 1+ (M = Mo) and 2+ (M = W) bearing (2-aminoethyl) diphenylphosphine (edpp), have been isolated and fully characterized. Molybdenum and tungsten halide precursors react with ... -
Synthesis, molecular and electronic structures of a paramagnetic trimetallic cluster containing an unusual Mo3(l3-Se)2(l-Se)3 core
Elsevier (2014)The electron precise [Mo3(l3-Se)(l-Se)3(dppe)3Br3] + incomplete cuboidal complex, with six cluster skeletal electrons (CSE), was converted into the paramagnetic bicapped [Mo3(l3-Se)2(l-Se)3(dppe)3] + cluster (1+ ), ...
