Refractive index of Si (Silicon) - Aspnes
When it comes to optics, silicon is transparent to infrared light, making it valuable for infrared lenses and other optical components. However, it's opaque to visible light. The material's versatility and abundance have made it integral to many industries, from construction to electronics and beyond.
A self-assembled, silicone acrylate coating formulation and …
Jan 16, 2019 · A newly synthesized, single-step silicone acrylate formulation cured by conventional radiation produced a reflection spectrum that showed an unusual interference pattern for a single-step coating. The acrylate was prepared by transesterification of silicate oligomer with ω-functionalized acrylic alcohol. The reflectance spectrum was analyzed ...

Optical absorption spectra were evaluated by diffuse reflectance spectra (DRS) and observed the maximum absorption around 450 nm. FTIR spectra were used to analyze the organic moieties...
Double-layer anti-reflection coating of SiO - IOPscience
Sep 9, 2020 · A highly transparent and super-hydrophilic double-layer anti-reflection coating was prepared by a simple and economical sol-gel method based on the glass substrate. The bottom and top layer were respectively made with SiO 2 –TiO 2 sol and SiO 2 –TiO 2 -PEG300 sol.
Characterization of silica gels by infrared reflection spectroscopy
The FTIR specular reflection spectra of porous silica gels, either dried at room temperature or subjected to partial densification at 400°C, are significantly different from the spectrum of bulk vitreous silica.
There is increasing interest in carbon-containing silicon compounds as precursors of high-performance ceramics. Accordingly, the table gives data on the infrared bands of some silicon-containing ceramics. This table presents empirical correlations between spectra and structure. The table does not show the types of vibrations (stretching,
