Effect of thiol on the holographic properties of TiO2 nanoparticle dispersed acrylate photopolymer films

In this paper we investigated the holographic properties by doping thiol into a TiO(2) nanoparticle dispersed acrylate photopolymer in green light with the recording intensity 80 mW cm(-2). It is found that the effect of oxygen inhibition on the polymerization was greatly reduced with the increase in thiol concentration. Additionally, noticeable improvements in the recording dynamics of Delta n together with the recording sensitivity by doping thiol into the TiO(2) nanoparticle dispersed acrylate photopolymer were obtained and the influence of the thiol groups on the diffusion of TiO(2) nanoparticles is also investigated.
