| 摘要: 利用丙烯酸和丙烯酸锌的共聚物作为前驱体，硫脲作为硫源，在溶剂热条件下于170 ℃反应96 h得到了ZnS纳米线束。透射电子显微镜(TEM)，选区电子衍射(SAED)和高分辨透射电子显微镜(HRTEM)测试表明这些线束是由单晶纳米线组装而成。该纳米结构具有很好的光学性质。傅立叶变换红外光谱(FTIR)结果证明纳米线被聚合物包裹。此外，对纳米线束的生长机理进行了简要讨论。 | |

| Abstract: ZnS nanowire bundles have been successfully synthesized by solvothermal method at a low temperature of 170 ℃ using a copolymer of acrylic acid (AA) and zinc acrylic acid (ZnAA) as the precursor. Transmission Electron Microscope (TEM), Selected Area Electron Diffraction (SAED) and High Resolution Transmission Electron Microscope (HRTEM) measurements show that these ZnS nanowire bundles are composed of single crystalline nanowires and the synthesized ZnS is of hexagonal wurtzite structure. The individual nanowire was encapsulated by polymer. This novel structure exhibits excellent optical properties. Furthermore, the formation mechanism has been proposed. | |
