RUI: Spectroscopic Study of Actinide Ions in Glasses

他们提出了对锕系元素掺杂无机玻璃光学性质的研究。特别是，他们将把注意力集中在这些很少被研究的系统的光激发和荧光动力学上。锕系元素的光学性质与镧系元素相似，镧系元素已广泛应用于光学器件中，但对锕系元素在玻璃中的光学性质的研究却很少。他们最初的任务将是进行实验，以表征有希望的锕系离子的光激发和发射光谱，以晶体宿主中的离子光谱为起点。如果实验在低温下进行，对这种光谱的解释就会更加清晰，因此将组装一个能够吸收和时间分辨荧光测量的光学系统。该系统的一些关键组件已经在Macalester到位，其余部分将在项目的第一年开发。

They propose a study of the optical properties of actinide doped inorganic glasses. In particular, they will focus their attention on the dynamics of optical excitation and fluorescence in these little studied systems. Though the actinides are similar in their optical properties to the lanthanides, which have been widely used in optical devices, there have been few studies of the optical properties of actinide ions in glasses. Their initial task will be to carry out experiments to characterize the optical excitation and emission spectra of promising actinide ions, using the spectra of ions in crystalline hosts as a starting point. Interpretation of such spectra are much clearer if experiments are carried out at low temperatures, so an optical system capable of absorption and time resolved fluorescence mearsurements will be assembled. Some of the key components of this system are already in place at Macalester, the rest will be developed in the first year of the project.
