*** 9712200 Potter This Phase I Small Business Technology Transfer project will investigate the intrinsic properties of a new phosphor material. There is a critical need for efficient low voltage phosphors for the continuing development of field emission displays (FED) to compete effectively with entrenched active matrix liquid crystal displays (AMLCDs). The proposer has recently developed a new low voltage blue cathodoluminescent phosphor as a thin film as well as a proprietary FED. Elevated temperature, and therefore expensive substrates, are required to integrate this new phosphor into the display device. To permit integration at lower temperature on less expensive substrates, such as glass or plastic, the new phosphor material will be synthesized utilizing ceramic techniques and then deposited using rf sputtering, which is a low temperature process. Process parameters will be optimized for low voltage cathodoluminescent efficiency and maximum luminosity. Detailed analysis of the new material will enable the incorporation of dopants that will provide spectral responses suitable for full color displays. Establishing viable processes to incorporate the phosphor into FEDs will lead to the Phase II objective of fabricating the proposer's FED in existing integrated circuit (IC) foundries. A wide variety of display technologies including field emission, electroluminescent, vacuum fluorescent, and surface conduction electron emitter display products. ***

*** 9712200波特 这个第一阶段的小企业技术转让项目将研究一种新的磷光体材料的内在特性。对于场致发射显示器（FED）的持续发展来说，迫切需要有效的低电压磷光体，以有效地与嵌入式有源矩阵液晶显示器（AMLCD）竞争。 该提案人最近开发了一种新的低电压蓝色阴极射线荧光粉作为薄膜以及专有的FED。 将这种新的磷光体集成到显示设备中需要升高的温度，因此需要昂贵的基板。 为了允许在较低温度下集成在较便宜的基板上，如玻璃或塑料，新的磷光体材料将利用陶瓷技术合成，然后使用射频溅射沉积，这是一种低温工艺。 将优化工艺参数以获得低电压阴极射线发光效率和最大发光度。 对新材料的详细分析将使掺杂剂的掺入成为可能，这将提供适合全色显示器的光谱响应。建立将荧光粉纳入FED的可行工艺将实现第二阶段目标，即在现有的集成电路（IC）代工厂中制造提议者的FED。 各种显示技术，包括场致发射、电致发光、真空荧光和表面传导电子发射显示产品。 ***
