他们提出了一个研究的光学性质的锕系元素掺杂 无机玻璃 特别是，他们将专注于 关注光激发和荧光的动力学 在这些很少被研究的系统中。 虽然锕系元素 类似于镧系元素的光学性质， 已广泛用于光学器件，但很少有 玻璃中锕系离子光学性质的研究。 他们的首要任务是进行实验， 表征的光激发和发射光谱 有前途的锕系离子，利用晶体中的离子光谱， 作为一个出发点。 这些光谱的解释是 如果在低温下进行实验， 因此能够吸收和时间分辨的光学系统 将组装荧光测量。 的一些关键 该系统的组成部分已经在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.
