Fabrication and characterizations of dandelions-like β -SrV2O6 micro-crystallites via hydrothermal process

摘要：

Sr-V-O materials made up of dandelions-like micro-crystallites with the diameter of around 0.5mm have been synthesized via a mild hydrothermal method in the presence of adipic acid at 220℃ for 60 hours. The micro-crystallites in general consist of well-arranged microrods with the average length of a few hundred micrometers and the diameters ranging 1 to 5 μm. Electron diffraction measurements revealed that these microrods have an orthorhombic structure as reported for β-SrV2O6 and grow along the <010> direction. The hydrothermal treating temperature and reaction compositions are found to have certain affects on the morphology of the products. A possible mechanism for the micro-pattering formation is proposed based on our systematical analysis.
