Photoinduced effects in hybrid sol-gel materials

Durability of SiO2–TiO2 Photocatalytic Coatings on Ceramic Tiles

“…In particular, to improve surface cleanability properties, the photocatalycity of TiO 2 nanoparticles has been used. In fact when exposed to radiation of adequate wavelength, titanium dioxide (TiO 2 ) shows peculiar characteristics such as photocatalysis of redox reactions, superhydrophilicity, and antibacterial properties . In the last 5 years, a large number of tile ceramic factories are trying worldwide to overcome some of the technological challenges in order to scale up the process and obtain a large‐scale application.…”

Dichroism of Poly(Methyl Methacrylate) Thin Films Doped with Disperse Orange 11 Molecules

“…Recently, photoinduced optical anisotropy in polymer/organic dye systems has been the subject of intensive investigations [3,4]. These materials are promising in the field of modern optics for optical recording, optically-controlled optical elements, optical switches, and so on.…”

“…These materials are promising in the field of modern optics for optical recording, optically-controlled optical elements, optical switches, and so on. Numerous studies on azo dyes incorporated in polymeric systems have been reported in the past two decades [3][4][5]. Anthraquinone dyes have also been under extensive research as well, since they have interesting optical properties.…”

Photoinduced Anisotropy in Poly(Methyl Methacrylate)/Sudan Red III Thin Films

“…Photoinduced optical anisotropy is of primary importance in the development of techniques dealing with light-controlled anisotropy, such as dichroism and birefringence. Materials with POA properties are very promising for use in many photonic applications; [1,2] for instance, for the production of polarization holographic optical elements, [3][4][5] polarization-sensitive wavefront phase conjugation, [6,7] etc. POA lies at the heart of the photoalignment (PA) technique which is employed in the manufacturing process of liquid crystal displays for fabricating high quality aligning substrates.…”
