We request funding of $68,407 for items needed to repair two fast Ti:sapphire laser systems and bring them up to performance specifications. These instruments have a replacement value of ca. $750,000 and are essential for maintaining and extending the research programs of the applicants. These lasers are used to investigate the fast dynamic behavior of highly excited electronic states of metalloporphyrins and related materials, in solution, in sols and gels and in polymer films and solid matrices. The results are of importance in the design and characterization of new materials for NIR solar energy capture and storage using non-coherent photon upconversion by triplet-triplet annihilation. These lasers are also used as light sources for multi-user fluorescence microscopy experiments mounted by the Saskatchewan Structural Sciences Centre, in particular for fluorescence lifetime imaging experiments.

我们申请68，407美元的资金，用于修复两个快速钛宝石激光系统并使其达到性能规格所需的项目。这些工具的重置价值约为100万美元。$750，000，对于维持和扩展申请人的研究计划至关重要。这些激光器用于研究金属卟啉和相关材料在溶液、溶胶和凝胶以及聚合物膜和固体基质中的高激发电子态的快速动力学行为。研究结果对设计和表征利用三重态-三重态湮灭实现非相干光子上转换的近红外太阳能捕获和存储新材料具有重要意义。这些激光器也被用作萨斯喀彻温省结构科学中心安装的多用户荧光显微镜实验的光源，特别是荧光寿命成像实验。
