我们演示并表征了 ZrO(2) 纳米粒子分散的丙烯酸酯光聚合物薄膜中的体积全息记录，该薄膜具有非常低的散射损失。与之前报道的TiO(2)纳米粒子分散的光聚合物相比，散射系数降低了三十多倍。结果表明，在纳米粒子浓度为15 vol.%时，可以获得高达5.3x10(-3)的折射率调制，并显着抑制光聚合收缩。还研究了纳米粒子浓度和光栅间距对折射率调制的依赖性。
We demonstrate and characterize volume holographic recording in ZrO(2) nanoparticle-dispersed acrylate photopolymer films that have very low scattering loss. More than thirty-fold reduction in the scattering coefficient, as compared with those of previously reported TiO(2) nanoparticle-dispersed photopolymers, is achieved. It is shown that the refractive index modulation as high as 5.3x10(-3), together with substantive photopolymerization-shrinkage suppression, is obtained at the nanoparticle concentration of 15 vol.%. Dependences of nanoparticle concentration and grating spacing on the refractive index modulation are also investigated.
