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.

这个小企业创新研究第一阶段项目提出了制备一类新的超快，高效的磷光体和闪烁体材料。为了重新获得显示器的竞争优势，磷光体必须在低电压和高电流下快速有效。纳米晶体技术（NCT）开发的高效和超快荧光粉将显着改善上述性能。NCT将开发高效和超快的蓝色，绿色和红色线发射稀土掺杂纳米晶体（DNC）磷光体。DNC荧光粉的独特性能可以实现具有高对比度和高分辨率的低成本、超薄、明亮的显示器。除了显示器应用之外，高效DNC磷光体中的超快速度可以导致极快的闪烁体材料。在拟议的第一阶段工作期间，NCT将使用室温化学制备技术开发和表征可见线发射磷光体。这项工作扩展到第二阶段将包括这些荧光粉在显示器和闪烁体系统中的性能评估。
