SBIR Phase I: Rare-Earth Ion Doped Polymer Materials for 3-D Volumetric Displays

9860615 该小型企业创新研究（SBIR）第一阶段项目旨在开发通过将稀土离子掺杂的有机络合物分散在可光聚合单体主体中来合成用于3D立体显示的大量双光子跃迁（TPT）材料的方法。尽管已经证明了使用稀土离子掺杂玻璃的基于双光子上转换的体积显示器，但是制造基于玻璃的大体积显示介质的困难阻碍了进一步的发展。所提出的努力将通过开发用于生产大量TPT材料的低成本、可扩展的合成方法来解决这一需求。 商业稀土有机配合物将与液体单体混合，然后通过W照射形成固体。这种方法的可行性和可扩展性将通过制作半球（直径6厘米）来证明。研究了掺Er ~（3+）聚合物的双光子吸收诱导荧光。为了确保新合成的材料将满足系统要求，将设计一个三维体积显示系统，以确定聚合物显示介质的浓度和其他参数。 大容量显示媒体将允许用于空中/地面交通控制、医学和科学3D可视化以及家庭娱乐的3D体积显示，其市场规模是巨大的。显著降低的成本、更高的离子密度和大批量生产的可扩展性使光聚合单体成为此类应用的理想主体材料。

9860615 This Small Business Innovation Research (SBIR) Phase I project aims to develop methods to synthesize large volumes of two-photon-transition (TPT) materials for 3-D volumetric displays by dispersing rare-earth ion-doped organic complexes in photopolymerizable monomer host. Although volumetric displays based on two-photon up-conversion using rare-earth ion-doped glass have been demonstrated, difficulty in manufacturing glass-based large volume display media has hindered further development. The proposed effort will address this need by developing a low-cost, scalable synthesis method for producing large volumes of TPT materials. Commercial rare-earth organic complexes will be mixed with liquid monomer, followed by W irradiation to form a solid. Feasibility and scalability of this approach will be demonstrated by producing a hemisphere (6-cm dia.) of Er3+-doped polymer and characterizing the two--photon absorption induced fluorescence. To ensure that newly synthesized material will satisfy system requirements, a 3-D volumetric display system will be designed to determine the concentration and other parameters for the polymer display media. Large volume display media will allow 3-D volumetric displays for air/ground traffic control, medical and scientific 3-D visualization and family entertainment, whose market sizes are enormous. Significantly lower-cost, higher ion-density, and scalability to large volume production make photopolymerizable monomers the ideal host materials for such applications.
