摘要：
We found that SiO2 nanoparticles dispersed in liquid polymethylsiloxane (PMS) exhibit unique optical nonlinearity in low-intensity visible radiation fields. The values of the nonlinear portion of the refractive index and absorption coefficient for nanoparticles increase to maxima, and then decrease to zero when the radiation intensity changes from 1 to 500 W/cm2. We estimated the electron energy structures for SiO2 nanoparticles dispersed in different liquid matrices (PMS, distilled water, and isopropyl alcohol) and explained the influence of the matrix permittivity value on this structure, as well as the optical properties of the nanoparticles.
