Abstract
Metallic thin-film materials and nanoparticles (mainly silver (Ag)-based) are recently being used in many nano-technological applications, including sensors, reflective heat-mirror coatings, and antibacterial coatings. The physical vapor deposition technique has attracted significant attention for Ag-based nanocomposites with tailoring of the structural and optical properties of metallic thin films, thus allowing for further improvements and application possibilities in various existing fields, namely electronics, catalysis, magnetics, and optics, alongside the environment and health and new emergent fields, particularly thin-film coatings. This study highlights the preparation, characterization, properties, and possible future application directions of several types of silver (Ag)-based nanocomposite thin films prepared by using physical vapor deposition techniques. The high-temperature (above 300 °C) heat-treated composite layer shows significant spectral shifts; however, distinguishingly notable sizes of nanoparticles are not observed, which indicates that this newly developed composite material can be useful for various coating applications.
Highlights
Nowadays, there is substantial scientific interest in the engineering and characterization of unconventional nanocomposite materials for various applications, ranging from construction to technological discovery [1,2,3,4,5,6,7]
building-integrated PV (BIPV) technologies are intended to combine energysaving and aesthetic features
In this work, we propose to develop a new nanocomposite-type thin-film material (Ag+ silicon carbide (SiC)) that can be found suitable for broadening the application range of thin-film materials in ultra-stable coating design options, with better control over their properties
Summary
There is substantial scientific interest in the engineering and characterization of unconventional nanocomposite materials for various applications, ranging from construction to technological discovery [1,2,3,4,5,6,7]. The degradation of the optical and physical properties of silver-based multilayer coating structures is mainly due to the stability problems affecting the thin metal layer. Material layers placed on top of ultrathin pure Ag layers have a tendency to “sink” into the gaps between the Ag nano-islands, altering the shape and effective optical thickness of these layers next to silver [1,13,17,18,19,20] In this nanotechnological century, these issues are an important subject matter for the studies intended to design, develop, and establish the optimized growth processes for ultra-thin and comparatively smoother layers of nanocomposite-type metallic materials (on arbitrary substrate sublayer types) to overcome the problems related to ultra-thin layer material growth.
