| 摘 要： | 采用水热法制备了纳米ZnFOH结构阵列，包括纳米柱阵列和纳米带阵列.研究了ZnFOH在不同条件下的沉积方式.在低酸碱度pH＝6.0时，在ZnO晶种基底上形成菱形纳米柱阵列，这源于正交晶体固有的结晶习性.在较高的酸碱度pH＝8.0时，由于Zn2＋优先吸附在原子核的(010)表面上，在Zn2＋基底上形成ZnFOH 纳米带阵列.NH4F作为控制剂调节ZnF＋的过饱和，这有助于基底上的非均相成核.

| Abstract: | 1D nanostructured ZnFOH arrays including nanoprism(NP) array and nanobelt(NB) array were fabricated by hydrothermal route. The deposition manner of ZnFOH on the different substrate has been investigated. At low pH＝6.0， rhombus NP array on the ZnO seed substrate is formed which originate from the intrinsic crystalline habit of orthorhombic crystal. At higher pH＝8.0， ZnFOH NB array on the Zn2＋ substrate is formed owing to the preferential adsorption on the (010) plane of the nucleus. NH4F plays a role as a control agent to accommodate the supersaturation of ZnF＋ which facilitates the heterogeneous nucleation on the substrate. |
