| 摘 要： | 以氯化锌、草酸钠和多酚为原料,通过沉淀反应及调节多酚浓度制得形貌可控的二水草酸锌晶体,再通过热分解得到三维自组装纳米氧化锌结构。分别用X射线衍射(XRD)、扫描电子显微镜(SEM)、热重-差热分析(TG-DTA)和荧光分光光度计(PL)对制备的样品进行表征。结果表明:随着多酚含量的增加,四方块状二水草酸锌出现了中空结构,当多酚浓度达到20mg/mL时晶体变成无规则的小碎块。当多酚含量为3.0mg/mL时,晶体尺寸最大。光致发光谱显示三维氧化锌发出很强的蓝绿光,并随着退火温度的升高而增强。 |

| Abstract: | Using ZnCl2, Na2C2O4 and polyphenols as the starting materials, 3D ZnO nano-structures were obtained by thermally decomposing zinc oxalate dehydrate crystal and tuning the concentration of polyphenols with precipitin reaction. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric-differential thermal analysis (TG-DTA) and the photoluminescence (PL) spectroscopy. The results indicate that the hollow structure in the zinc oxalate dihydrate exhibits with the increase of the content of polyphenols. When the concentration of polyphenols is 20mg/mL, the crystals have no fixed shape, but only lots of disorder and unsystematic small pieces are formed. When the concentration of polyphenols is 3.0mg/mL, the crystal size achieves to the maximum value. The photo-luminescence tests show that synthetic 3D ZnO nano-structures exhibit strong blue-green emission, which can be strengthened with the increases of annealing temperature. |
