Paper Abstract

In this paper we present a study of the photoinduced anisotropy in novel nanocomposite films of azopolymers doped with ZnO nanoparticles with different sizes – 50 and 100 nm. The photoresponse was evaluated by classical polarimetric setup with two crossed polarizers, recording laser with wavelength 473 nm and probe He-Ne laser. Our experimental results indicate that doping with both 50 and 100 nm sized particles improves the response time, however the smaller size nanoparticles provide increase of Δnmax with up to 40%, as the 100 nm particles reduce the saturated value of the birefringence, due to the higher scattering.
