Our research programs are focused on the development and understanding of new materials with optical properties of interest in visible, near and short-wavelength infrared for a new generation of computers, telecommunication systems, sensors, and healthcare devices. NSERC RTI funds are requested for the acquisition of a time-resolved photoluminescence (TRPL) system that is urgently needed for the applicant team to provide training opportunities, to advance our research programs, and to enhance our publication records and international research profiles. The Edinburgh Instruments FS5 system (customized for this project) has been chosen as a cost-effective solution offering light emission measurements for liquid and solid (thin film) samples over an extended wavelength range (200-1700nm), for lifetimes in the 2.5 ns - 100 us range, and at low temperatures (77-300K). The system offers different detectors with sensitivity in the visible, near- (NIR) and short-wave infrared (SWIR) ranges, which are critical for the development of new materials for Si photonics, optoelectronics, bioimaging, and sensing, and for understanding their fundamental properties in the time domain. While Western has photoluminescence spectrometers designed for the visible range, light detection capabilities in these extended wavelengths (NIR and SWIR) are not currently available and this is a bottleneck for progress in our research. This system offers a user-friendly interface accessible to non-experts, and does not require significant experience in optics. This accessibility will facilitate training of a core group of 42 HQP across seven different research groups at Western in the Departments of Physics and Astronomy, Chemistry, Mechanical and Materials Engineering, and Chemical and Biochemical Engineering. This instrument will also support several international research projects and university-industry partnerships. The new time-resolved photoluminescence system will bring new capabilities for parametric studies of novel materials over a broad range of temperatures and wavelengths. Fundamental properties of new materials that can be revealed with this system will open new possibilities for many applications in electronic-photonic integrated circuits and sensors important for the Materials and Manufacturing sectors in Canada.

我们的研究计划的重点是对新一代计算机，电信系统，传感器和医疗保健设备的可见，近乎和短波长度的光学特性的开发和理解。要求NSERC RTI资金以获取时间分辨的光致发光（TRPL）系统，该系统迫切需要申请人团队提供培训机会，促进我们的研究计划，并增强我们的出版记录和国际研究资料。 Edinburgh Instruments FS5系统（为该项目定制）被选为一种具有成本效益的解决方案，可在扩展波长范围（200-1700nm）（200-1700nm）上为2.5 ns-100 US范围以及低温（77-300k）的寿命提供液体和固体（薄膜）样品（200-1700nm）。该系统提供了不同的检测器，在可见的，近（NIR）和短波红外（SWIR）范围内具有敏感性，这对于开发用于SI光子学，光电学，生物成像和感应的新材料以及了解其在时域中的基本特性至关重要。尽管西部具有专为可见范围设计的光致发光光谱仪，但目前尚不可用这些扩展波长（NIR和SWIR）的光检测功能，这是我们研究进展的瓶颈。该系统提供了一个可以通过非专家访问的用户友好界面，并且不需要光学方面的大量体验。这种可及性将有助于培训在物理和天文学，化学，机械和材料工程以及化学和生化工程的西部七个不同研究小组中的42个HQP核心组。该工具还将支持几个国际研究项目和大学 - 工业伙伴关系。新的时间分辨的光致发光系统将在广泛的温度和波长中为新材料的参数研究带来新的能力。可以用该系统揭示的新材料的基本特性将为对加拿大材料和制造业很重要的电子光综合电路和传感器中的许多应用开放新的可能性。
