The deposition of coatings of Au and ZnO nanoparticles (NPs) on glass, semiconductor silicon, polyethylene terephthalate, and polystyrene substrates was studied. Deposition was carried out using relatively concentrated dispersions of particles in ethanol (approximately 5–10 mM Au, ZnO), which showed limited time resistance to coagulation and sedimentation, but returned to their original dispersed state by ultrasonic treatment before each cycle of deposition of NPs. The NPs of Au and ZnO were stabilized by abietate and acetate ions, respectively. Simple coatings from Au or ZnO NPs and a combined coating from a mixture of Au and ZnO NPs, as well as two-layer combined coatings with alternating layers of Au/ZnO and ZnO/Au NPs, were obtained by drop casting and the proposed method of deposition from the capillary layer of the dispersion with the use of a linker. The formation of coatings on transparent substrates was studied by means of UV–Vis spectroscopy. Coatings were characterized by SEM, EDX, XRD, PL, UV–Vis and surface resistance methods. The effect of heat treatment on coatings characteristics was tested.

研究了在玻璃，半导体硅，聚对苯二甲酸乙二醇酯和聚苯乙烯基板上的金和锌纳米粒子（NPs）涂层的沉积。沉积使用相对集中的乙醇分散液（约5-10 mM Au，ZnO）进行，这显示出有限的抗凝结和沉淀时间，但在每个NP沉积周期之前通过超声处理恢复到其初始分散状态。松香酸根和乙酸根离子分别稳定了Au和ZnO的NP。由Au或ZnO NP构成的简单涂层，以及由Au和ZnO NP混合物构成的组合涂层，以及具有Au / ZnO和ZnO / Au NP交替层的两层组合涂层，通过滴铸法和使用连接剂从分散体的毛细管层中沉积的拟议方法获得了这些产物。通过紫外可见光谱研究了透明基材上涂层的形成。通过SEM，EDX，XRD，PL，UV-Vis和表面电阻方法对涂层进行了表征。测试了热处理对涂层特性的影响。
