Abstract
- In this study, the deposition and characteristics of Si- and Ti-series multilayer coatings with respective glass/Si 3 N 4 /NiCr/Ag/NiCr/Si 3 N 4 and glass/TiO 2 /ZnSnO 3 /ZnO/Ag/NiCrO x /ZnSnO 3 /Si 3 N 4 structures were investigated. Experimental analyses were performed, and the optical performance and thermal stability of the coatings were assessed. The as-deposited Si- and the Ti-series samples exhibited optimal shading coefficient of 0.49 and 0.57, respectively. Thermal annealing in air was performed to analyze the thermal stability and oxidation resistance of the samples. The Si- and Ti-series samples prevented the failure of low-emissivity properties at 700 and 600 °C, respectively. In addition to high transparency, the Si-series samples exhibited improved low-emissivity properties, reduced light pollution, and superior thermal stability compared to the Ti-series samples. The use of Si 3 N 4 and NiCr layers effectively prevented the oxidation and cracking of the Ag layer upon heat treatment. This study presents the characteristics of Si- and Ti-series samples for energy-saving building applications. [ABSTRACT FROM AUTHOR]
