The Study of Sputtered Silver-Based Low-Emissivity Coating on Glass
Two types of low-emissive coatings were deposited onto glass substrates by magnetron sputting method, which were designed as Ag and TiO2/Ni-Cr/Ag/Ni-Cr/TiO2. The transmittance and thickness of the samples were measured by TH1901 spectrophotometer and NKD-8000V ellipsometer. Fourier transform infrared spectrometer (FTIR) was employed to detect the low emissivity properties, it demonstrated that the silver-based multilayer coatings showed an efficient heat isolation due to their low emissivity properties. And they had a good performance in the visible range compared to the single Ag layer according to the transmittance spectra as well. The surface morphology of the samples was investigated by scanning probe microscope (SPM), it was determined that the Ag layer formed a homogeneous grain size when deposited onto the Ni-Cr layers.
