- Abstract
This paper is focused on optical nonlinearity in CdS nanostructured thin films, which was reviewed comprehensively and discussed in detail along with future perspective. Due to third harmonic generation in CdS materials on exposed to highly intense light that is significant feature to develop modern photonics devices. CdS chalcogenide semiconductor binary compound is one of the most particularly promising candidate for nonlinear optical applications due to their enhanced nonlinear optical properties in thin films. CdS nanostructured thin films have been shown exceptional third order nonlinear optical (TONLO) behavior near the sub band gap energy region. This review will be based on TONLO properties of CdS nanostructured thin films, which will focus on the tailoring of TONLO properties as a function of particle size, dopant and CdS polymer nanocomposite. Doping and size effect in CdS system is the important opportunity to develop it with excellent TONLO properties. This review paper will give an open area of research possibilities to search the efficient nonlinear optical CdS nanostructured thin films for advanced modern photonics applications and also will provide an idea to develop efficient materials with exceptional TONLO properties.
