This project, using combinatorial search methods to discover and fabricate new phosphors for flat panel displays, aims at developing new methodologies toDiscover new phosphor materials and Actually identify new materials that have attractive properties for flat displays.The general approach consists of using electrodeposition as a means of preparing new inorganic phosphor materials (e.g. oxides, silicates, aluminates, phosphates, etc.) that vary in composition over wide range of values. Because of the multicomponent nature of these phosphates (typically containing three or four different metals), the number of compositions that must be examined to effectively map compositional space for a given class of materials may be many thousands. The effort comprises activities in several distinct areas:Synthesis of new metal-containing precursors that can be used in electrodeposition,Development of electrodeposition methods that can be used as the substrate for electrodeposition,Development of a microelectrode array that can be used with the new precursor metal complexes, as the substrate electrodepositions,Actual phosphor deposition using the methods and precursors just described,Parallel testing of the emission characteristics of the arrays of phosphors, andBulk synthesis and characterization of the most promising materials.The expected outcomes of the effort include:Development of new approaches for rapidly discovering phosphors,Identification of new materials that have attractive properties for flat panel displays, andDevelopment of a long-term materials discovery and characterization effort at University of Wyoming (UW), that will dovetail with the institution and state's efforts at fostering the establishment and maintenance of a viable science and high technology based in the State.The effort involves 3 researchers at UW and one at Blue Sky Applied Technologies, Inc. (BSAT).

该项目使用组合搜索方法来发现和制造用于平板显示器的新型荧光粉，旨在开发新的方法来发现新的荧光粉材料并实际识别对平板显示器具有有吸引力的性能的新材料。一般方法包括使用电沉积作为制备新型无机荧光粉材料（例如氧化物、硅酸盐、铝酸盐、磷酸盐等）的手段，这些材料的成分在很宽的范围内变化。 价值观。由于这些磷酸盐的多组分性质（通常含有三种或四种不同的金属），必须检查以有效绘制给定类别材料的成分空间的成分数量可能有数千种。这项工作包括几个不同领域的活动：合成可用于电沉积的新型含金属前体、开发可用作电沉积基底的电沉积方法、开发可与新前体金属配合物一起用作基底电沉积的微电极阵列、使用刚刚描述的方法和前体进行实际磷光体沉积、发射的并行测试 荧光粉阵列的特性，以及最有前途材料的批量合成和表征。这项工作的预期成果包括：开发快速发现荧光粉的新方法，鉴定对平板显示器具有有吸引力特性的新材料，以及怀俄明大学（UW）开展长期材料发现和表征工作，这将与该机构和国家促进建立荧光粉的努力相结合 这项工作涉及威斯康星大学的 3 名研究人员和蓝天应用技术公司 (BSAT) 的一名研究人员。
