Time-resolved photoluminescence facility for materials research in Montréal

这一基础设施将成为蒙特里萨伊新材料物理和化学协同研究的核心设施。其独特的能力将从其多学科产出中产生当地和区域利益，其形式是有机（非金属）半导体、无机半导体（如许多现代电子设备中发现的半导体）和生物系统的光物理特性的科学和技术的国际领先研究。这项研究将导致纳米科学的重大进步，并将有助于设计更好的电子材料。通过这笔拨款获得的设备可以观察到极快的事件，实时发生的时间尺度短至一秒的几分之一（百万分之一秒）。本研究中使用的主要技术是时间分辨光致发光光谱，其中短激光脉冲“激发”所研究的系统，并且在激发后测量材料发出的光作为时间的函数。这使得解开激发态的命运成为可能，这反过来又为研究材料的电子特性提供了一个窗口。与加拿大创新基金会资助的其他相关实验技术相结合，一个强大的研究新材料的武器库可供蒙特里萨大学和附近机构的研究人员使用。这项拨款将使首席研究员和设备制造商Axis-Photonique Inc.之间进行强有力的合作。该公司可以使用我们强大的实验设备来进一步开发他们的产品。这将为加强区域和国家对科学和技术发展的贡献，提高公司和合作研究人员的国际知名度，并为曲海的财富创造作出贡献提供重要机会。

This infrastructure will form the core facility for concerted research in the physics and chemistry of novel materials in Montréal. Its unique capabilities will have local and regional benefits arising from its multidisciplinary output in the form of internationally leading research on the science and technology of organic (non-metal containing)semiconductors, inorganic semiconductors (such as those found in many modern electronic devices), and photphysical properties of biological systems. This research will result in significant advances in nanoscience and will aid in the design of better electronic materials. The equipment acquired with this grant allows observation of extremely fast events, occurring on timescales as short as a fraction of a second (a millionth of a millionth of a second) in real time. The principal technique used in this research is time-resolved photoluminescence spectroscopy, where a short laser pulse 'excites' the system under study, and the resulting light emitted by the material is measured as a function of time after the excitation. This allows unravelling of the fate of the excited state, which in turn provides a window into the electronic properties of the materials under investigation. In conjunction with other related experimental techniques funded by the Canada Foundation for Innovation, a powerful arsenal for the study of novel materials is available to investigators in the Université de Montréal and in nearby institutions. A strong collaboration between the principal investigator and the manufacturer of the equipment, Axis-Photonique Inc. based in Québec, will result from this grant. The company has access to our powerful experimental facility in order to develop their product further. This will lead to a significant opportunity to strengthen regional and national contributions to science and technology development, enhance the international visibility of the company and the co-investigators, and contribute to wealth creation in Québec.
