LIGHT INDUCED THERMODIFFUSION OF NANOPARTICLES

Abstract

We have analyzed the optical transmittance response of thin cell with liquid containing absorbing nanoparticles in a Gaussian beam field. The transmittance spatial changing is caused by the thermal diffusion phenomenon (Soret effect) which produces the variations of concentration of absorbing nanoparticles.
