SBIR Phase II: Nanoparticle Photostimulated Luminescence Based Optical Storage

这个小型企业创新研究（SBIR）第二阶段项目将展示在纳米颗粒中产生光激发光（PSL）的能力。PSL磷光体在数字成像和存储方面的潜在应用，包括X射线成像，可能是重要的。目前使用的PSL磷光体存在几个缺点，包括与传统的屏-膜方法相比更高的费用和更差的分辨率。纳米颗粒的量子限制为现有PSL磷光体的许多缺点提供了解决方案。该项目将对纳米颗粒进行表征，目标是优化这些材料以用作薄膜中的荧光粉。该项目还将制造所需的薄膜，并将其与市售的PSL磷光体进行性能、寿命和其他感兴趣的因素的比较。商业应用将广泛适用于数字成像，提供高分辨率、低成本、易于存储、低复杂性、易于携带和其他理想的功能。具有高效PSL的材料在诸如光学存储、X射线成像、辐射测量和质量控制、光学剂量计和测年、红外传感器、图像增强器、近红外到可见光转换器以及生物分子结构记录和探测等技术应用中具有巨大的潜力。

This Small Business Innovative Research (SBIR) Phase II project will demonstrate the ability to generate photostimulated luminescence (PSL) in nanoparticles. The potential applications in digital imaging and storage offered by PSL phosphors, including X-ray imaging could be significant. PSL phosphors currently in use present several drawbacks including greater expense and poorer resolution as compared to conventional screen-film methods. The quantum confinement of nanoparticles offers solutions to many of the shortcomings of existing PSL phosphors. The project will characterize nanoparticles with a goal of optimizing these materials for use as phosphors in thin films. The project will also fabricate the required thin films and compare them to commercially available PSL phosphors for performance, longevity, and other factors of interest.The commercial applications will be widely applicable to digital imaging, offering high resolution, low cost, easy storage, low complexity, easy portability, and other desirable features. Materials with efficient PSL have great potential for technical applications such as optical storage, X-ray imaging, radiation measurements and quality control, optical dosimeters and dating, infrared sensors, image intensifiers, near-infrared-to-visible light converters, and bio-molecular structure recording and probing.
