Repair and upgrade of the UV-Vis-NIR fluorometer with intergrating sphere and time-resolved capability

我们寻求资金紧急维修和升级2014年获得NSERC-RTI赠款的UV-VIS-近红外荧光仪，以继续和完成我们正在进行的先进光电材料和设备的研究。该提议的两个主要特点是：(I)取代能够测量固体样品的绝对发光量子产额的积分球；(Ii)使用时间分辨光谱学模块进行升级，从而能够在非常宽的(毫秒)时间范围内进行寿命测量和时间门控光谱学。这些功能与(现有的)近红外探测器相结合，将使该仪器不仅在麦吉尔，而且在该地区都是独一无二的。该仪器将成为一个部门设施，由共同申请者的研究小组和麦吉尔化学和魁北克先进材料中心的其他成员广泛使用(目前的用户群包括11个学术小组)。它将继续为每年20多名学生的培训做出贡献。*由请求的维修和升级实现的能力对于继续在几个具有基础科学重要性的领域的研究进展至关重要。具体地说，该仪器将用于开发：一类新的有机室温荧光粉、发光共价有机骨架、光驱动和上转换材料，以及在现有技术(传感器、生物成像和可再生能源(光伏))中的一系列有用应用，以及新技术的开发(如有机注入激光)。这些都是共同申请者和主要用户的主要优势领域。该仪器提供的培训将显著促进我们的HQP的推广，他们将熟悉材料设计和合成、光谱/光物理和设备工程。考虑到加拿大在光子学方面的历史优势，这些都是加拿大工业需要的技能。**

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.**
