Synthesis and Compactness Dependence on Flower-like Copper Germanate

摘要

Flower-like CuGeO_(3) has been obtained using a simple hydrothermal process by controlling the compactness.X-ray diffraction shows that the flower-like CuGeO_(3) is composed of orthorhombic CuGeO_(3) phase.Scanning electron microscopy displays that the size of each flower-like CuGeO_(3) is about 3 μ which consists of the accumulation of dozens of CuGeO_(3) nanorods with the diameter and length of less than 100 nm and about 1 μ, respectively.Compactness dependence results demonstrate that the compactness is the key factor for the formation of flower-like CuGeO_(3).Free-standing CuGeO_(3) nanowires can be obtained by improving the compactness.Hydrothermal temperature and reaction time have important roles on the size and formation of the flower-like CuGeO_(3).
