Abstract
In this paper, plasma silver (Ag) modified zinc oxide (ZnO) (AZO) was used to form AZO nanomaterials (including AZO nanofilms (NFm), AZO nanowires (NWs) and AZO nanoflowers (NFw)) in a two-step-controlled manner to investigate the effect of compounding different contents of Ag on the linear optical aspects of ZnO materials. The growth mechanism of the AZO nanomaterials with different strategies is discussed. If Ag nanoparticles (NPs) grow on the ZnO NFm surface, they first grow with ZnO as the core and then self-core into islands, which are undoubtedly influenced by factors such as the growth mechanism of ZnO as well as Ag. If Ag is grown on the surface of the ZnO NWs and ZnO NFw, it is more likely to self-core owing to factors such as the roughness of the ZnO NWs and ZnO NFw surfaces. The AZO nanomaterials have excellent optical properties based on the surface plasmon resonance, local electromagnetic field and charge transfer mechanism between Ag and ZnO. With the increase in Ag content, the absorption edges of AZO NFm are red-shifted, and the absorption edges of AZO NWs and AZO NFw are first blue-shifted and then red-shifted. The results show that AZO nanomaterials prepared using different methods not only have different growth morphologies, but also have different optical properties with potential for the preparation of optical devices. The plasmonic AZO nanomaterials in a two-step-controlled manner to investigate the effect of compounding different contents of Ag on the linear optical aspects of ZnO materials.![]()
