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，以紧急维修和升级2014年获得NSERC-RTI赠款的紫外可见近红外荧光光谱仪，继续并完成我们正在进行的先进光电材料和器件的研究。该提案的两个主要特点是：（i）更换积分球，使固体样品的绝对发光量子产率的测量和（ii）升级与时间分辨光谱模块，使寿命测量和时间门控光谱在非常广泛的（纳秒毫秒）的时间范围。这些功能，结合（已经存在的）近红外探测器将使该仪器不仅在麦吉尔，而且在该地区独一无二。该仪器将成为一个部门的设施，由麦吉尔化学和魁北克先进材料中心的共同申请人和其他成员的研究小组广泛使用（目前的用户群包括11个学术团体）。它将继续为每年培训20多名学生做出贡献。这次维修和升级所带来的能力对于继续在具有重要科学意义的若干领域取得研究进展至关重要。具体而言，该仪器将用于开发：一类新的有机室温磷光体，发光共价有机框架，光致动和上转换材料，在现有技术（传感器，生物成像和可再生能源（光致发光））以及新技术（例如，有机注入激光器）的开发中具有广泛的有用应用。这些是共同申请人和主要用户的主要优势领域。该仪器所实现的培训将显著有助于我们的HQP的推广，他们将在材料设计和合成，光谱/电子物理学和器件工程方面变得舒适。考虑到加拿大在光子学方面的历史实力，这些都是加拿大工业所需要的技能。
