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中的几个关键研究项目，这些项目由NSERC Discovery Grant和NSERC创建赠款资助。其中包括（1）太阳能电池的BN掺杂单线裂变染料； （2）开发有机光发射二极管（OLEDS）和氧感觉设备的高效和健壮的蓝色发射器，包括磷光过渡金属复合物以及热活化的延迟荧光（TADF）染料； （3）用于包括OLED在内的有机光电子的BN掺杂的多芳族杂环（BN-PAHS）。为了建立单裂裂变染料，磷光发射剂或TADF发射器的关键参数，对于OLEDS或氧气传感器，绝对有必要将常规访问与时间分辨的磷光仪相关。时间分解的磷光仪允许从染料分子确定衰减寿命和能量，这是理解结构和性质关系的关键，新功能发光材料的逻辑设计和开发以及我们研究计划的进步以高竞争性的方式。拟议的光谱仪是对10名研究生的研究，一名博士后研究生和本科生在王实验室的研究必不可少的工具。学生通过对拟议的光谱仪的动手操作获得的高级分析知识和技能将使他们在就业市场上具有竞争优势。**
