The use of titanium dioxide nanoparticles to control the refractive index of the photoresist $\mathrm{SU}$-$8$ for the synthesis of three-dimensional photonic crystals

The effect of titanium dioxide nanoparticles on the optical properties of the suspensions is studied in the article. The effective refraction index of titanium dioxide nanoparticles is calculated. Nanocomposite material synthesis, consisting of $\mathrm{SU}$-$8$ photoresist and nanoparticles $\mathrm{TiO}_2$ is obtained. This material demonstrates low light scattering with volume filling factor $0,38$ and value of the refraction index which is about $1,97$.
