Investigations on TiO2 Based Nanocomposites as Potential Photonic Materials

Abstract

Nano materials with large third-order nonlinear susceptibility and#967;(3) and ultrafast response have been under continuous scientific interest because of their potential applications for all-optical switching, light-controlled phase, refractive index modulation and optical power limiting devices. These nano materials can be inorganic, organic or various combinations of both classes of materials. Such nano scale composite materials containing metal oxides have been continuously focussed by the research community for their impending claims in the field of optoelectronic devices. In particular, TiO2 has gained widespread acclaim for its prospective applications such as, in dye sensitized solar cells, photo catalysts, gas sensors, electro-chromic devices, biomaterials and so on. In this context, this thesis has been devoted for the detailed investigation of TiO2 and TiO2 based nanocomposites materials. The present thesis has been organized into seven chapters with its each chapter describing different aspects of TiO2. newline
