Time-resolved photoluminescence facility for materials research in Montréal

该基础设施将成为蒙特利尔新材料物理和化学协同研究的核心设施。其独特的能力将使当地和区域受益于其多学科产出，其形式是国际领先的有机（含非金属）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研究。这项研究将导致纳米科学的重大进展，并将有助于设计更好的电子材料。用这笔赠款获得的设备可以观察极快的事件，发生在真实的时间中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学，其中短激光脉冲“激发”所研究的系统，并测量激发后材料发射的光随时间的变化。这允许解开激发态的命运，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，蒙特利尔大学和附近机构的研究人员可以使用强大的新材料研究武器库。主要研究者和设备制造商Axis-Photonique Inc.之间的密切合作。在魁北克，将产生这种赠款。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。这将带来一个重要的机会，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者的国际知名度，并为魁北克创造财富做出贡献。

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.
