Rayleigh scattering study and particle density determination of a high refractive index TiO₂ nanohybrid polymer

We have experimentally carried out a Rayleigh scattering study of a high refractive index TiO₂ nanohybrid polymer. By employing the Rayleigh scattering technique with at least three different wavelengths, we can obtain the Rayleigh ratio of the TiO₂ nanohybrid polymer at each utilized wavelength. These measured Rayleigh ratios are then used to estimate the size of the nanoparticle and determine the number of nanoparticles per unit volume or particle density. Furthermore, this technique can be used to evaluate the dominant size of nanoparticles in the nanohybrid polymer mainly contributed to Rayleigh scattering.
