U.S.-Caribbean Cooperative Research: Preparation and Spectroscopy of Macrocyclic Complexes Containing Pairs of Rare Earth Ions

这项美洲计划奖将支持杜兰大学的加里·L·麦克弗森博士和牙买加西印度群岛大学的I.A.卡瓦博士继续开展研究合作。研究了一系列含稀土离子对的新型大环配合物的发光光谱和激发态动力学。虽然许多大环稀土配合物的发光性质已经被研究过，但许多最重要的激发态行为特征还没有被探索。该项目将提供关于这些复合体及其相互作用的有价值的新信息。这些特殊材料的制备和结构表征将由西印度群岛大学的Kawha博士完成，而材料的发光将在杜兰的激光光谱实验室进行检测。该项目还将涉及两所大学的本科生和研究生。

This Americas Program award will support continuation of a research collaboration between Dr. Gary L. McPherson of Tulane University and Dr I. A. Kawha of the University of the West Indies, Jamaica. The research focuses on the luminescence spectroscopy and excited state dynamics of a series of novel macrocyclic complexes containing pairs of rare earth ions. Although the luminescence properties of a number of the macrocyclic rare earth complexes have been examined, many of the most important features of excited state behavior have not been explored. This project will provide valuable new information about these complexes and their interactions. Preparation and structural characterization of these unusual materials will be accomplished by Dr. Kawha at the University of the West Indies, while the luminescence of the materials will be examined in the laser spectroscopy laboratories at Tulane. This project will also involve undergraduate and graduate students from both institutions.
