Bis(piperidinedithiocarbamato)copper(II) was used as a precursor for the synthesis of copper sulfide nanoparticles in solutions of different compositions derived from: dodecanethiol (DT), oleylamine (OLA) and trioctylphosphine (TOP) which can be viewed as components acting as, solvents, surfactants or ligands. The powder‐X‐Ray diffraction of the nanoparticles showed predominately roxbyite, and/or djurleite phase based on the solvent mixture used, and covellite or dignite in OLA depending on the temperature. The morphology changed from spherical to hexagonal discs with variation of the solvent from DT to DT/TOP (2:1) mixture. Thin films of copper sulfide were also deposited by the Aerosol Assisted Chemical Vapour Deposition (AACVD). Djurleite was the only phase deposited by AACVD (350, 400 and 450 °C). Cubes, short rods and spherical microstructures were observed in the SEM images, with average size increasing with temperature.

双（哌啶二硫代氨基甲酸酯）铜（II）配合物的硫化铜纳米粒子制备及AACVD沉积薄膜相控制的新实例

双（哌啶二硫代氨基甲酸酯）铜（II）被用作在以下组成的不同组成的溶液中合成硫化铜纳米粒子的前体：十二烷硫醇（DT），油胺（OLA）和三辛基膦（TOP），可以看作是，溶剂，表面活性剂或配体。纳米粒子的粉末X射线衍射显示，主要取决于混合溶剂，方铁矿和/或菱锰矿相，OLA中的依维石或褐铁矿取决于温度。随着溶剂从DT到DT / TOP（2：1）混合物的变化，形态从球形变为六角形。硫化铜薄膜也通过气溶胶辅助化学气相沉积（AACVD）沉积。Djurleite是AACVD（350、400和450°C）沉积的唯一相。立方体，
