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。这些包括（1）用于太阳能电池的BN掺杂的单线态裂变染料;（2）用于有机发光二极管（OLED）和氧传感装置的高效和稳健的蓝色发射体的开发，包括磷光过渡金属络合物和热活化延迟荧光（TADF）染料;（3）用于有机光电子学（包括OLED）的BN掺杂的多芳族杂环（BN-PAH）。为了建立用于OLED或氧传感器的单线态裂变染料、磷光发射体或TADF发射体的关键参数，绝对有必要对时间分辨磷光计进行常规访问。时间分辨磷光计可以确定染料分子的磷光发射的衰变寿命和能量，这是了解结构与性能关系、新型功能发光材料的逻辑设计和开发以及推进我们的研究的关键。以高度竞争的方式进行研究计划。该光谱仪是王教授实验室10名研究生、1名博士后和1名本科生研究的必备工具。学生通过实际操作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的竞争优势。**
