SGER: Excited-State Decay Dynamics of Gas Phase Europium(III) Complexes

南达科他州大学的Mary Berry教授受实验物理化学计划的支持，研究气相镧系化合物的激发态衰变动力学。这些实验代表了光谱分子束方法首次应用于镧系配合物的研究，补充了其他关于碱、碱土和过渡金属的研究。共振增强多光子电离（REMPI）光谱将用于研究铕（III）与有机配体的配合。最初的重点将是在这些分子系统中检测REMPI的可行性。这些气相研究将允许光谱学和动力学来确定没有晶体应变和溶剂和离子相互作用的复杂因素。镧系化合物在能源应用中很重要，例如用作激光器的材料。对这些化合物的光谱学的更深入的了解将有助于开发新的光学材料。PI在指导印第安学生方面有着出色的记录。

Professor Mary Berry of the University of South Dakota is supported by the Experimental Physical Chemistry Program to study the excited state decay dynamics of vapor phase lanthanide complexes. These experiments represent the first application of spectroscopic molecular beam methods to the case of lanthanide complexes, complementing studies by others on alkali, alkaline earth and transition metals. Resonance Enhanced Multiphoton Ionization (REMPI) spectroscopy will be employed to investigate europium (III) complexed with organic ligands. The initial focus will be on the feasibility of REMPI detection in these molecular systems. These gas phase studies will allow the spectroscopy and dynamics to be determined without the convoluting factors of crystal strain and solvent and ion interactions. Lanthanide compounds are important in energy applications and are used as materials for lasers, for example. A more thorough understanding of the spectroscopy of these compounds will prove useful in developing new optical materials. The PI has an excellent mentoring record including Native American students.
