The proposed spectrometer supports several key research projects in our group that are funded by an NSERC discovery grant and an NSERC CREATE grant. These include (1) BN-doped singlet fission dyes for solar cells; (2) the development of highly efficient and robust blue emitters for organic light emitting diodes (OLEDs) and oxygen sensory devices including phosphorescent transition metal complexes and thermally activated delayed fluorescent (TADF) dyes; (3) BN-doped polyaromatic heterocycles (BN-PAHs) for organic optoelectronics including OLEDs. To establish the key parameters for either singlet fission dyes, phosphorescent emitters or TADF emitters for OLEDs or oxygen sensors, it is absolutely necessary to have routine-access to a time-resolved phosphorimeter. The time-resolved phosphorimeter allows the determination of decay lifetimes and energy of phosphorescent emission from the dye molecules, which are the key to understanding the relationship of structures and properties, the logical design and development of new functional luminescent materials, and the advancement of our research program in a high competitive manner. The proposed spectrometer is an indispensable tool for the research of 10 graduate students, one postdoctoral fellow and undergraduate students in Wang's lab. The advanced analytical knowledge and skills acquired by students through their hands-on operation of the proposed spectrometer will give them a highly competitive edge in the job market.**

拟议的光谱仪支持我们小组的几个关键研究项目，这些项目由 NSERC 发现补助金和 NSERC CREATE 补助金资助。其中包括（1）用于太阳能电池的氮化硼掺杂单线态裂变染料； (2) 开发用于有机发光二极管（OLED）和氧传感器件的高效、稳定的蓝色发射体，包括磷光过渡金属配合物和热激活延迟荧光（TADF）染料； (3)用于有机光电器件（包括OLED）的氮化硼掺杂多芳香族杂环化合物（BN-PAH）。为了确定 OLED 或氧传感器的单线态裂变染料、磷光发射器或 TADF 发射器的关键参数，绝对有必要常规使用时间分辨磷光计。时间分辨磷光计可以测定染料分子磷光发射的衰变寿命和能量，这是理解结构和性能关系、新型功能发光材料的逻辑设计和开发以及我们的进步的关键。以高度竞争的方式进行研究计划。所提出的光谱仪是王实验室10名研究生、1名博士后和本科生研究中不可或缺的工具。学生通过动手操作所提议的光谱仪获得的先进分析知识和技能将使他们在就业市场上具有高度竞争优势。 **
