SBIR Phase II: Nanoparticle Photostimulated Luminescence Based Optical Storage

这个小型企业创新研究（SBIR）二期项目将展示在纳米颗粒中产生光激发光（PSL）的能力。PSL荧光粉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。与传统的屏幕膜方法相比，目前使用的PSL荧光粉存在一些缺点，包括更高的费用和较差的分辨率。纳米粒子的量子约束解决了现有PSL荧光粉的许多缺点。该项目将对纳米颗粒进行表征，目标是优化这些材料作为薄膜荧光粉的使用。该项目还将制造所需的薄膜，并将其与市售的PSL荧光粉进行性能、寿命和其他感兴趣的因素的比较。其商业应用将广泛适用于数字成像，具有高分辨率、低成本、易于存储、低复杂性、易于携带等特点。具有高效PSL的材料在光学存储、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、生物分子结构记录和探测等技术应用方面具有巨大的潜力。

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.
