title: Controlled synthesis, characterizations and structural-properties of micro-flowers, pine-cone, core-shell and liver-like micro-architecture of crystalline ZnMn2O4.
abstract: The conspicuous ZnMn2O4 micro-structures have been synthesized by hydrothermal method by using Mn3O4 and Zn powder as precursors. The micro-structures of the ZnMn2O4 could be tuned by changing the reaction time only in the reaction system. The final products have been characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis and the Raman spectroscopy. Room temperature Raman spectroscopy investigation indicates that the synthesized micro-structures have strong fundamental vibrational modes. The intensity of the vibrational modes varied with change in the reaction time in the synthesized products of ZnMn2O4. The mechanism of this peculiar Raman property was analyzed.
