9861313 This Small Business Innovation Research Phase I Project is to synthesize a series of new conjugated polymers as active materials for solid state polymer lasers. Recent efforts to make diode lasers from semiconducting polymers are hindered by limitations to net gain, which include photoinduced absorption (PA), concentration quenching and self-absorption. Dilute blends of conjugated polymers, the subject of this proposal, can solve these problems through Forster energy transfer. We are going to synthesize a series of alkoxyphenyl-PPV and alkylphenyl-PPV as the host polymer to demonstrate and develop conjugated polymer blends as high gain/low loss laser materials and to optimize the Forster energy transfer from host to guest. Successful completion of the project will provide polymers with properties of higher molecular weight and good solubility, high photoluminescence efficiency, good compatibility and maximum spectra overlap with the guest polymers. Subsequently, in Phase II, photo-pumped stimulated emission will be used to guide the fabrication of the electrical pumped laser devices. The research will make an important contribution to development of efficient, robust materials providing light weight, low power addressable arrays of light sources for a broad range of applications from simple alphanumeric displays to high information content flat panel displays.

9861313 这个小型企业创新研究第一阶段项目是合成一系列新型共轭聚合物作为固态聚合物激光器的活性材料。最近用半导体聚合物制造二极管激光器的努力受到净增益限制的阻碍，其中包括光致吸收（PA）、浓度猝灭和自吸收。本提案的主题是共轭聚合物的稀共混物，可以通过福斯特能量转移解决这些问题。我们将合成一系列烷氧基苯基-PPV和烷基苯基-PPV作为主体聚合物，以演示和开发作为高增益/低损耗激光材料的共轭聚合物共混物，并优化从主体到客体的福斯特能量转移。该项目的成功完成将为聚合物提供更高分子量、溶解性好、光致发光效率高、相容性好以及与客体聚合物最大光谱重叠等性能。随后，在第二阶段，光泵受激发射将用于指导电泵浦激光器件的制造。 该研究将为开发高效、坚固的材料做出重要贡献，为从简单的字母数字显示器到高信息内容平板显示器的广泛应用提供轻质、低功耗的可寻址光源阵列。
