Doped Nanocrystals: A New Class of Phosphors and Scintillators

这个小型企业创新研究第一阶段项目建议制备一种新型的超快、高效的荧光粉和闪烁体材料。为了在显示器领域重新获得竞争优势，荧光粉必须在低电压和大电流下快速高效。利用纳米晶技术(NCT)开发的高效超快荧光粉将显著改善上述性能。NCT将开发高效和超快的蓝、绿、红线发射稀土掺杂纳米晶(DNC)荧光粉。DNC荧光粉的独特特性可能导致具有高对比度和高分辨率的低成本、扁薄、明亮的显示器。除了显示应用，高效DNC荧光粉的超快速度还可以导致极快的闪烁体材料。在拟议的第一阶段工作中，NCT将利用室温化学制备技术开发和表征可见线发射荧光粉。这项工作扩展到第二阶段将包括对这些荧光粉在显示和闪烁体系统中的性能进行评估。

This Small Business Innovation Research Phase I project proposes to prepare a new class of ultrafast, efficient phosphor and scintillator materials. To regain the competitive edge in displays, the phosphors must be fast and efficient at low voltages and high currents. The efficient and ultrafast phosphors developed by Nanocrystals Technology (NCT), will improve the above properties significantly. The NCT will develop efficient and ultrafast blue, green and red line-emitting rare-earth doped nanocrystalline (DNC) phosphors. The unique properties of the DNC phosphors could lead to a cost-effective, flat-slim, bright display with high-contrast and high-resolution. In addition to display applications, the ultrafast speed in efficient DNC phosphors can lead to extremely fast scintillator materials. During the proposed Phase I effort, NCT will develop and characterize the visible line-emitting phosphors using room temperature chemical preparative techniques. The extension of this work to Phase II will include the performance evaluation of these phosphors in display and scintillator systems.
