Increasing photosensitizer concentration has been considered as an effective approach to improve the performance of holographic material. In this paper, we report on new method for increasing the saturated dissolvability of photosensitizer PQ within polymeric media by introducing copolymerization monomer into the PQ/PMMA. The photosensitizer concentration of PQ was increased from 0.7wt% to 1.3wt%, compared with the typical PQ/PMMA sample. Besides, we investigated performance of polarization holographic recordings in typical PQ/PMMA and copolymerization monomer-containing PQ/PMMA with the orthogonally polarized signal and reference waves. And the doping of THFMA component resulted in a significant improvement of diffraction intensity and photosensitivity. In addition, high-quality holographic image reconstruction was realized in our home-made material.
提高光敏剂浓度被认为是改善全息材料性能的有效方法。在本文中,我们报道了一种通过将共聚单体引入PQ/PMMA中来提高光敏剂PQ在聚合物介质中饱和溶解度的新方法。与典型的PQ/PMMA样品相比,PQ的光敏剂浓度从0.7wt%提高到了1.3wt%。此外,我们研究了在典型的PQ/PMMA和含共聚单体的PQ/PMMA中使用正交偏振信号和参考波进行偏振全息记录的性能。并且THFMA组分的掺杂导致衍射强度和光敏性有显著提高。此外,我们在自制材料中实现了高质量的全息图像重建。
