We seek funding to urgently repair and upgrade the UV-Vis-near-IR spectrofluorometer acquired in 2014 with a prior NSERC-RTI grant, to continue and complete our on-going studies of advanced optoelectronic materials and devices. The two key features of the proposal are: (i) replacement of the integrating sphere that enables measurements of absolute luminescence quantum yield of solid samples and (ii) upgrade with a time-resolved spectroscopy module which enable life-time measurements and time-gated spectroscopy in the very broad ( nsec msec) temporal range. These features, combined with (already existing) near-infrared detector will make this instrument unique not only at McGill but also in the region. The instrument will become a departmental facility, used extensively by research groups of co-applicants and other members of McGill chemistry and Quebec Center for Advanced Materials (current users base comprises 11 academic groups). It will continuously contribute to training of 20+ students each year.******The capabilities enabled by this requested repair and upgrade are critical for continuing the research progress in several fields of fundamental scientific importance. Specifically, the instrument will be used to develop: a new class of organic room temperature phosphors, luminescent covalent organic frameworks, photo-actuating and up-converting materials with a spectrum of useful applications in the existing technologies (sensors, bioimaging, and renewable energy (photovoltaics)) as well as the development of new ones (eg, organic injection lasers). These are the key areas of strength of the co-applicants and major users. The training enabled by the instrument will contribute prominently to generalization' of our HQP who will become comfortable in materials design and synthesis, spectroscopy/photophysics and device engineering. These are the skills in demand by Canadian industry, considering its historic strength in photonics.**

我们寻求资金以紧急修复和升级2014年以前的NSERC-RTI赠款收购的UV-VIS-NEAR-IR SpectroFluorometer，以继续并完成我们对先进的光电材料和设备的正在进行的研究。该提案的两个关键特征是：（i）更换集成球体，该球体可以测量实心样品的绝对发光量子产率，以及（ii）用时间分辨的光谱模块升级，该模块可实现寿命测量，并在非常广泛的（NSEC MSEC）临时范围内进行寿命测量和时间门控光谱。这些功能，结合（已经存在的）近红外探测器将使该乐器不仅在McGill，而且在该地区都独一无二。该工具将成为一个部门设施，由共同申请人和麦吉尔化学的其他成员和魁北克高级材料中心的其他成员广泛使用（当前用户基础包括11个学术组）。它将每年不断促进20多名学生的培训。******通过此要求的维修和升级所实现的功能对于继续在基本科学重要性的几个领域继续研究进展至关重要。具体而言，该仪器将用于开发：一类新的有机室温荧光粉，发光的共价有机框架，照片演示和向上转换材料，以及在现有技术（传感器，生物影像学，生物影像学和可再生能量（Photovoltaics））以及新的（EG Ongecection egection new Organice Intrasecection）中的有用范围（传感器，生物影像学和可再生能量（Photovoltaics））。这些是共同申请者和主要用户的力量的关键领域。该仪器对培训的培训将为我们的HQP的概括做出重大贡献，他们将在材料设计和合成，光谱/光体物理学和设备工程方面变得舒适。这些是加拿大行业的需求技能，考虑到其在光子学中的历史优势。**
