Zn(II), Cd(II) and Hg(II) dithiocarbamate complexes have been synthesized and characterized by elemental analysis, thermogravimetric analysis, UV-Vis, FTIR, (1)H- and (13)C NMR spectroscopy. The complexes were thermolysed at 180 °C and used as single molecule precursors for the synthesis of HDA capped ZnS, CdS and HgS nanoparticles and polymethylmethacrylate (PMMA) nanocomposites. The optical and structural properties of the nanoparticles and nanocomposites were studied by UV-Vis, PL, XRD and SEM. The crystallites sizes of the nanoparticles varied between 3.03 and 23.45 nm. SEM and EDX analyses of the nanocomposites confirmed the presence of the nanoparticles in the polymer matrix.
已通过元素分析、热重分析、紫外可见光谱、傅里叶变换红外光谱、(1)H 和(13)C 核磁共振光谱对 Zn(II)、Cd(II) 和 Hg(II) 二硫代氨基甲酸盐配合物进行了合成和表征。在 180°C 下对配合物进行热解,并将其用作合成 HDA 封端的 ZnS、CdS 和 HgS 纳米粒子和聚甲基丙烯酸甲酯(PMMA)纳米复合材料的单分子前体。通过紫外可见光谱、PL、XRD 和 SEM 研究了纳米粒子和纳米复合材料的光学和结构性质。纳米粒子的晶粒尺寸在 3.03 到 23.45nm 之间。纳米复合材料的 SEM 和 EDX 分析证实了纳米粒子在聚合物基质中的存在。
