用低温化学溶液法在100℃制备了非层状结构的单晶ZnO纳米带.在反应初期先形成层状结构的碱式醋酸锌(Zn(OH)_(2-x)(CH_3COO)_xnH_2O)前驱体,然后在水热条件下使其转化成单晶ZnO纳米带.用透射电子显微镜(TEM),场发射扫描电子显微镜(FESEM)、X射线衍射(XRD)、高分辨透射电子显微镜(HRTEM)和荧光光谱(PL)对ZnO纳米带的形态,结构和光学性质进行了表征.结果表明,在上述反应中醋酸根阴离子和弱有机碱六次甲基四胺(HMT)对前驱体和ZnO纳米带的形成起了关键作用.
Single-crystalline ZnO nanobelts with non-layered structure were synthesized by the solution route at 100 ℃ based on the transformation of the layered precursor (Zn(OH)_(2-x)(CH_3COO)_x nH_2O).The morphology, structure and optical property of the ZnO nanobelts were characterized by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and photoluminescence (PL),respectively. It is indicated that the acetate anion and the weak organic alkali hexamethylenetetramine (HMT) play the critical role in the formation of the layered precursors at the beginning of the process.
