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.
