Investigation of Structural and Nonlinear Optical Properties of Nanostructured Materials for Optoelectronic Applications

Abstract

The primary goal of the thesis is to investigate the nonlinear optical behaviour of synthesized nanomaterials and interaction with electromagnetic radiation. Our research study focuses on the synthesized of metal tungstatenanoparticles doped with rare earth and alkaline metal ions and to evaluate the nonlinear optical. The nanostructured materialsare prepared using chemical and sol-gel techniques. The synthesized nanostructured materials was characterized using powder X-Ray Diffraction (XRD), UV-Vis DRS spectrophotometer, photoluminescence spectroscopy (PL) Scanning Electron Microscopy (SEM), Raman spectroscopy, Transmission Electron Microscopy (TEM), and Energy- dispersive spectrometer (EDS) to study their physio-chemical properties of the prepared nanomaterials. Later, the work is focused on the investigation of on nonlinear properties using cw laser source at 532 nm with an automated z-scan set up. To investigate the research findings from the above mentioned systematic work, our thesis involves three chapters which targets on evaluating the nonlinear applications newline
