Low Temperature Time-Resolved Photoluminescence System for Visible, Near- and Short-Wavelength Infrared

我们的研究项目专注于开发和理解具有可见光、近波长和短波长的新材料，用于新一代计算机、电信系统、传感器和医疗保健设备。NSERC RTI基金被要求购买一个时间分辨率的光致发光（TRPL）系统，申请团队迫切需要提供培训机会，推进我们的研究计划，并提高我们的出版记录和国际研究形象。爱丁堡仪器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）内对液体和固体（薄膜）样品进行光发射测量，寿命范围在2.5 ns - 100 us范围内，低温（77-300K）。该系统提供了不同的探测器，在可见光，近红外（NIR）和短波红外（SWIR）范围内具有灵敏度，这对于开发用于硅光子学，光电子学，生物成像和传感的新材料以及了解其在时域中的基本特性至关重要。虽然西方有专为可见光范围设计的光致发光光谱仪，但这些扩展波长（近红外和SWIR）的光探测能力目前还不可用，这是我们研究进展的瓶颈。该系统提供了一个用户友好的界面访问非专家，不需要在光学显著的经验。这种可访问性将促进对西部大学物理与天文、化学、机械与材料工程、化学与生物化学工程等七个不同研究小组的42名HQP核心小组的培训。该工具还将支持若干国际研究项目和大学-工业伙伴关系。新的时间分辨光致发光系统将为在广泛的温度和波长范围内对新材料进行参数化研究带来新的能力。通过该系统可以揭示新材料的基本特性，这将为电子-光子集成电路和传感器的许多应用开辟新的可能性，这对加拿大的材料和制造业至关重要。

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.
