摘要
用油胺作为溶剂、六水合硝酸锌作为锌源、硫代乙酰胺作为硫源,采用溶剂热法分别在160℃、170℃、180℃下合成了ZnS纳米棒。利用分子荧光光度计、X-射线衍射仪、扫描电子显微镜及能量色散X-射线光谱仪对样品的荧光性能、晶体结构、晶体形貌和元素含量分别进行了表征。结果表明:在170℃下得到直径为200nm六方晶系的ZnS纳米棒荧光性能最好;在激发波长为393nm、发射波长为450nm时,发出明亮的蓝色荧光。将170℃下得到的ZnS纳米棒与环氧树脂(EP)复合,得到ZnS/EP复合薄膜,其荧光效应和发射波长与ZnS纳米棒相比几乎没有改变。
Using oleylamine as a solvent, zinc nitrate hexahydrate as a zinc source, and thioacetamide as a sulfur source, ZnS nanorods were prepared by a solvothermal method at 160℃, 170℃ and 180℃, respectively. The fluorescence property, crystal structure,crystal morphology,and element content of obtained samples were characterized respectively by molecular fluorescence photometer,X-ray diffractometer, scanning electron microscope,and energy dispersive spectrometer. The results indicated that, the ZnS nanorod with hexagonal system obtained at 170℃ had the size of 200 nm,and its fluorescence property was the best;the ZnS nanorod with the 393 nm excitation wavelength and 450 nm emission wavelength emitted bright blue fluorescence. Besides,compared with ZnS nanorods,the fluorescence property and emission wavelength of the composite film ZnS/EP(epoxy resin) which obtained by ZnS nanorods combined with epoxy resin at 170℃ was almost unchangeable.
