Morphological Evolution of SrMoO₄Crystals from Wires to Notched Spheres through Oriented Attachment

Understanding the oriented-attachment growth of nanocrystals from an energy point of view: a review

“…The diameters of both the NRs and the NCs are approximately 7.5 nm at t ¼ 180 min. Further kinetic analysis via eqn ( 6) and (7) shows that both the OR mechanism and the single step OA model (eqn ( 6)) cannot explain the experiment result. A two-step OA reaction mechanism was then found to work well, indicating that a multi-level OA mechanism 83,86 have no ligands or other adsorbed species, the signicance of DI in NP-NP growth remains elusive, especially in those occurring in a chemical environments with polar solvent, ions and ligands.…”

“…d t is equal to 3.1 nm at a growth time of 180 min. By analyzing the growth kinetics using eqn ( 6) and (7), it is found that OA governs the growth process since the monotonous increase in d t predicted according to eqn (7) is not observed in the experiment. This result veries that the growth is mainly NP-NP OA growth.…”

A two-dimensional four-fold symmetric SrMoO4 dendrite

“…35,36 A variety of SrMoO 4 crystal morphologies, including fishbone-like, octahedral, double taper-like, penniform, and nanorod morphologies, have been obtained using precipitation, hydrothermal reactions, and microemulsion processes. [37][38][39][40][41] Relatively little is known about the evolutionary morphologies of hierarchical SrMoO 4 superstructures. This paper reports a method for evolving the morphologies from a tetragonal bipyramid to a two-dimensional (2-D) four-fold symmetric dendrite by adjusting the solvothermal reaction conditions in a water-hexane bilayer system.…”

Synthesis of SrMoO4 microstructures by the microwave radiation‐assisted chelating agent method

“…SrMoO 4 is one of the most important metal molybdates with scheelite-type tetragonal structure, and is also widely used in typical areas as photoluminescent materials [2][3][4][5][6][7], high active catalysts [8,9], and hosts for lanthanide activated lasers [10,11] and so on. For SrMoO 4 micro/nanostructures, many researches have performed on the synthesis of the material via various methods such as solid-state process [12,13], microwave radiation [3,[14][15][16], hydrothermal/solvothermal process [3,4,[17][18][19], microemulsion synthesis [5,20,21], co-precipitation method [22,23], sonochemical technology [7,24], electrochemical process [25][26], combining sol-gel and solid-state route [6], and pulsed laser deposition [27]. Compared with these methods, microwave radiation processing has received intense attention owing to the obvious merits: [28][29][30][31][32][33][34][35][36][37] (1) improved the diffusion process for the products through absorbing the electromagnetic energy, (2) gained very fast heating rates with little temperature gradient ...…”
