“…small particle size and thin film soft chemistry techniques are desired. YAG and rare earth doped YAG thin films and powders have been produced by various techniques, such as electrochemical synthesis, 15 spray-inductively coupled plasma, 16 plasma spray process, 17 pulsed laser deposition (PLD), 18 sol-gel [19][20][21] and metal-organic chemical vapour deposition (MOCVD). 22 In order to achieve desirable properties of the thin films, precise control of phase homogeneity, particle size and morphology is necessary.…”

“…A solution of ferroelectric nanowires of titanium based compound like BaTiO 3 (at a high concentration) and polymer can be mixed together and placed in a small electric field to orient them in the desired direction. Such a combination also exhibits a liquid crystal phase [130]. A great deal of research is being carried out on the synthesis of high quality transparent films consisting of polymer-titanium dioxide hybrid nanocomposites and their optical properties.…”

Abstract:Metal containing polymers are of great interest as they have proven to be the most promising materials for applications such as microelectronics, holography and magnetic recording of information. Metal containing polymers also provide an alternative to even the specialty glass materials conventionally used for optical applications. Metals such as barium, lead and lanthanum have been used to improve the optical properties such as refractive index and mechanical properties such as hardness of optical plastics. The metal-containing optical plastic materials with improved refractive index of as much as 1.60 along with the Abbe number of more than 30 have been successfully designed using these metals by the authors of this paper. To further increase the refractive index without any drop in Abbe number and to improve the hardness of the polymer matrix, titanium would be the most promising metal. Incorporation of titanium in plastic matrices to form homogeneous and optically clear compositions is a challenging task. This paper reviews the state-ofthe-art by which titanium can be dispersed in polymer matrices to form metal containing composites as optical plastics.

Novel way of making high refractive index plastics; metal containing polymers for optical applications

Abstract:Plastics are being preferred in almost all possible applications of materials. Several new applications including optical devices are being developed using plastics replacing conventional materials like inorganic glass etc. For the optical applications, the most important properties of plastics essential for their desired performance include refractive index, Abbe number, optical clarity, etc. The biggest challenge in developing suitable materials for optical applications has always been to meet the criteria of high refractive index along with a high Abbe number. Normally, if the refractive index increases, the Abbe number automatically decreases. The researchers have tried several approaches to deal with this typical challenge without which it is not possible to develop novel optical plastics. Presently the most popularly known optical plastics includes polymers such as polymethacrylates, polyurethanes, polycarbonates, polystyrene and diethylene glycol bis allyl carbonate. The latest material of high refractive index plastics with a refractive index of 1.67 belongs to the polythiourethanes chemistry. Several approaches are being tried world over, to develop materials of high refractive index. One of the approaches being pursued for enhancement of refractive index of existing monomers pertain to the incorporation of metals or metal salts in the matrices. The other commonly tried but difficult to achieve approaches pertain to the preparation of nanoparticles or nanocomposites.
