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

该小型企业创新研究（SBIR）一期项目旨在通过在可光聚合的单体主体中分散稀土离子掺杂有机配合物，开发用于三维体积显示的大体积双光子跃迁（TPT）材料的合成方法。虽然基于稀土离子掺杂玻璃的双光子上转换的体积显示已经被证实，但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。提出的努力将通过开发一种低成本、可扩展的合成方法来生产大量的TPT材料来解决这一需求。商业稀土有机配合物将与液体单体混合，然后W照射形成固体。该方法的可行性和可扩展性将通过生产一个半球（直径6厘米）的Er3+掺杂聚合物和表征双光子吸收诱导荧光来证明。为了确保新合成的材料能够满足系统的要求，我们将设计一个三维体积显示系统来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/地面交通管制、医疗和科学三维可视化以及家庭娱乐的三维体积显示，其市场规模巨大。低成本、高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宿主材料。

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.
