项目摘要
This project is aimed at extending the performance of AC electroluminescent (ACEL) phosphor powders for a wide range of display applications.Currently the best ACEL phosphor powders can be made into devices that have working lives around 2000-3000 hours at reasonable brightness in subdued lighting. Along with our partner companies (Pelikon and Kodak UK Ltd.) we will investigate the reasons for their degradation (both coated ar uncoated phosphors) so that a full understanding of the factors limiting their lifetimes and brightness can be understood. This study is timely because: some of the techniques necessary to do this work have only become available to the non-specialist in the last 5 years or so. For instance, using Rarr microscopy, it will be possible to examine the interfaces between the transparent coatings and the phosphor surfaces in individual particles under a variety of working conditions in a range of different chemical environments.Using new solution methods for precipitating phosphor precursor powders (homogeneous precipitation methodology) developed in the Centre for Phosphors and Display Materials at the University of Greenwich (again in the last 5 years, hence timely), so we will synthesise new ACEL phosphor powders that have improved brightness levels and longer lifetimes. This will be achieved by incorporating into the phosphor design changes both in concentration and distribution of active light-emitting centres from knowledge gained through understanding the current state-of-the-art. Fine control the number and distribution of these centres is possible from our new methods of precipitation from solution. We will also develop methods of coating the powders to further extend their lifetimes making use of our understanding of the role of the coating in commercial phosphors. Polymeric supports will be used to control particle size and morphology. The new synthetic technology developed at Greenwich will be scaled up for industrial production the laboratories of Kodak UK Ltd. We will work with Kodak UK Ltd. to transfer the technology developed at the University of Greenwich to their plant industrial production.
该项目旨在扩展交流电致发光(ACEL)荧光粉的性能,以用于广泛的显示应用。目前最好的ACEL荧光粉可以制成在柔和照明下在合理亮度下工作寿命约为2000-3000小时的器件。沿着我们的合作伙伴公司(Pelikon和柯达英国有限公司)我们将研究它们退化的原因(两种涂覆的AR未涂覆的磷光体),从而可以理解限制它们的寿命和亮度的因素的充分理解。这项研究是及时的,因为:在过去的5年左右,非专业人员才能获得进行这项工作所需的一些技术。例如,使用放射性显微镜,将有可能在各种不同的化学环境中的各种工作条件下检查单个颗粒中的透明涂层和磷光体表面之间的界面。(均匀沉淀法)在格林威治大学的磷光体和显示材料中心开发(再次在过去5年,因此及时),所以我们将合成新的ACEL荧光粉,具有改善的亮度水平和更长的寿命。这将通过在荧光粉设计中加入通过了解当前最新技术而获得的知识来改变活性发光中心的浓度和分布来实现。通过我们从溶液中沉淀的新方法,可以精细控制这些中心的数量和分布。我们还将开发涂层粉末的方法,以进一步延长其使用寿命,利用我们对涂层在商业荧光粉中的作用的理解。聚合物载体将用于控制粒度和形态。在格林威治开发的新合成技术将在柯达英国有限公司的实验室扩大规模,用于工业生产。我们将与柯达英国有限公司合作,将在格林威治大学开发的技术转移到他们的工厂工业生产中。
