A method is devised for the synthesis of nanosized silver particles in a polymethylmethacrylate matrix, and the optical properties of the resulting metal containing nanocomposites are studied. The possi bility of using the nanocomposites derived as antiglare and antireflection screen coatings is shown experimen tally.
The results of investigations into monolayered antireflective coatings based on silicon dioxide (sil ica) nanoparticles obtained according to the sol gel technology using a simple and efficient technique of dip ping into a sol of soda lime glass are presented. The influence of silica sol synthesis parameters and the size of the deposited nanoparticles on the structure and properties of the obtained coatings are revealed.
The paper presents two types of broadband antireflection coatings (AR) for silica glass in the range of optical wavelengths from 400 nm to 1000 nm. Dense and porous AR coatings based on silica nanoparticles (NPs) of different structure were produced by sol-gel process. Thick film AR coating consisted of silver NPs in the matrix of poly(methyl methacrylate) (PMMA) was obtained on the substrate by liquid-phase deposition method. Synthesis conditions of the coatings materials of specified structure are revealed. The linear refraction and the linear absorption of these media at the different wavelength depending on the technology of preparation of coatings are analyzed. An increase in optical transmittance of silica glass with the coatings was up to 8-10% in comparison with the uncoated substrate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
