Optical filters from SiO2 and TiO2 multi-layers using sol–gel spin coating method
Sol–gel spin coating process is used to produce optical filters from SiO2 and TiO2 multilayers. By coating the films symmetrically on both sides of the glass substrates, we designed two types of three-layer anti-reflective (AR) filters for the near–infrared region, and a ninelayer reflective filter for the near–UV region. We develop a simple theoretical model for these filters, which incorporat...
متن کاملSynthesis and Characterization of SiO2-Carbon Nanotube Hybrides Using a Sol-Gel Method
This work is focused on synthesis of SiO2- CNT hybrides via sol-gel method. Homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (CNTCOOH) with active silicic acid followed by titration to the solution of sodium silicate (Na2SiO3) under the average temperature condition of 80?C. Different ratios of multi-walled carbon nanot...
متن کاملSynthesis and characterization of maleimide-functionalized polystyrene-SiO2/TiO2 hybrid nanocomposites by sol–gel process
Maleimide-functionalized polystyrene (PSMA-SiO2/TiO2) hybrid nanocomposites were prepared by sol-gel reaction starting from tratraethoxysilane (TEOS) and titanium isopropoxide in the solution of polystyrene maleimide in 1,4-dioxane. The hybrid films were obtained by the hydrolysis and polycondensation of TEOS and titanium isopropoxide in maleimide-functionalized polystyrene solution followed by...
متن کاملSynthesis and characterization of the Pt/SiO2 nanocomposite by the sol-gel method
The silica supported platinum nanoparticles was synthesized by using the sol-gel method. The possibility of using diamminedinitro platinum (II) as Pt precursor and effect of metal precursor concentration on the final Pt nanoparticle size was investigated. A stable silica sol was prepared via hydrolysis of tetraethyl orthosilicate (TEOS) as a metal alcoxide and condensation reaction. Subsequentl...
متن کاملCharacterization and photocatalytic activity of SiO2-TiO2 mixed oxide nanoparticles prepared by sol-gel method
SiO2-TiO2 mixed oxides have been prepared by sol-gel technique from titanium tetraisopropoxide and tetraethylorthosilicate. The prepared materials were characterized by X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy, nitrogen physisorption and UV-vis diffuse reflectance spectroscopy. The results indicate that compared to pure TiO2, the SiO2-TiO2 mixed oxides show higher the...
