AN INVESTIGATION OF NONLINEAR OPTICAL PROPERTIES OF Au, TiO2 AND Au@TiO2 NANOPARTICLES PRODUCED BY PLAL TECHNIQUE

Abstract
Abstracts - In this work,Au, TiO2 and Au@TiO2 nanoparticles have been produced by applying a green production technique called femtosecond laser ablation in liquid. For optical application and development of novel techniques based on some novel materials gains more and more importance for life relieves of peoples. In this view of science, semiconductor materials as well as optical materials give great opportunities to develop some novel product in high technology to present expected properties such as low energy consumption and high efficiency. The first of all, Au, TiO2 and Au@TiO2 nanoparticles have been produced for whether we can open some novel applications for this very common material. Their structural, morphological, electrical and optical properties have been investigated and obtained results have been interpreted. Nonlinear optical properties of Au, TiO2 and Au@TiO2 nanoparticles have been produced and nonlinear optical properties have been presented within the scope of this presentation. Linear absorbance range, nonlinear absorption coefficient, nonlinear refractive index as well as third order nonlinear susceptibility have been investigated and a conclusion due to these results have been given too. Keywords - Nl Optics, Third Order Susceptibility, Nl Absorption Coefficient, Nl Refractive Index
