Abstract
Abstract In this research, MWCNT-BaTiO3/silica nano-composites were synthesized and analyzed at different MWCNTs loadings (2, 4, 6, and 8% wt). Utilizing the different concentrations of MWCNTs, the optical responses of MWCNT-BaTiO3/silica nanocomposite were investigated. For this purpose, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy were used. Using the Kramers-Kronig method, the refractive index and dielectric coefficient of MWCNT-BaTiO3/silica nanocomposites were analyzed. Results clearly revealed that the higher incorporation of MWCNTs in nanocomposites led to more strong responses in the real parts of both refractive index and dielectric coefficient. Finally, the transversal (TO)/longitudinal (LO) phonon frequencies shifted to the blue wavenumbers by decreasing the amount of MWCNTs in MWCNT-BaTiO3/silica nanocomposite.
