摘要
A variety of SrMoO4 morphologies were prepared by performing a solvothermal reaction in water-hexane bilayer solutions. The morphology of SrMoO4 crystals evolved from tetragonal bipyramidal to two-dimensional (2-D) four-fold symmetric dendrites as the reaction temperature and the MoO42-ion to Sr2+ ion reaction concentration ratio were increased. As the reaction temperature increased, the intensity ratio of the (004) to (112) XRD peaks increased dramatically, confirming that the morphology changed from a tetragonal bipyramid to a 2-D four-fold symmetric dendrite. Each of the 2-D four-fold symmetric SrMoO4 dendrites featured four long trunks along the <110> directions and a series of two branches perpendicular to the trunk. A possible crystal growth mechanism for the 2-D four-fold symmetric dendrites was proposed based on the crystallographic evidence.
