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阶段I项目是将一系列新的共轭聚合物综合为固态聚合物激光器的活性材料。净增益的局限性阻碍了从半导体聚合物制造二极管激光器的最新努力，其中包括光诱导的吸收（PA），浓度淬灭和自我吸收。该提案的主题的共轭聚合物的稀释混合物可以通过福斯特能量转移来解决这些问题。我们将合成一系列烷基氧苯基-PPV和烷基苯基-PPV作为宿主聚合物，以证明和发展共轭聚合物混合物作为高增益/低损耗激光材料，并优化从福特斯特的能量转移从宿主到来宾。该项目的成功完成将为聚合物提供较高的分子量和良好的溶解性，高光致发光效率，良好的兼容性和最大光谱与来宾聚合物重叠的特性。随后，在第二阶段，将使用弹式刺激的发射来指导电动泵送激光器设备的制造。 这项研究将为开发高效，健壮的材料的开发做出重要贡献，从而为从简单的字母数字显示到高信息内容的平面平板显示器提供了广泛的应用。
