Synthesis of 3D nanostructured flower-like ZnO architecture on ZnO thin-film by hydrothermal process

ZnO buffer 박막층 위에 성장된 3차원 ZnO 나노구조체의 합성

Recently, the control of size, morphology and dimensionality in inorganic materials has been rapidly developed into a promising field in materials chemistry. 3D nanostructured flower-like ZnO architecture with different size and shapes have been simply synthesized via a hydrothermal process, using zinc acetate and ammonium hydroxide as reactants.[1] In this study, the Zno thin-films were deposited by RF magnetron sputtering in other to get high adhesion and uniformity of 3D nanostructured flower-like ZnO architecture on a $SiO_2$ substrate. The XRD patterns identified that the obtained the nanocrystallized ZnO architecture exhibited a wurtzite structure. SEM images illustrated that the flower-like ZnO bundles consisted of flower-like or chestnut bur, which were characterized by polycrystalline and [0001] preferential orientation.
