Implementation of Raman and Other Modern Spectroscopies in the Upper-Level Physics Undergraduate Laboratories

现代分子光谱学和微观分析实验最近在UCF (Am。物理学报，62,429-434(1994))将被引入中高级本科实验室。本科学生正在学习的技能，如材料表征微拉曼光谱，这将给他们提供有用的知识，为他们准备研究生院或进入就业市场。他们正在利用过去十年来在这一领域发生的技术革命，使小型、低成本、高通量的仪器成为可能。这些实验非常适合本科课程，因为它们使学生能够研究基本的物理现象以及许多有用的应用。实验室配备了一台采用固态激光激发的拉曼光谱仪和一个显微镜附件。在中级实验中，学生将有使用多通道检测的吸收、发射和荧光的实践经验。实验在先进的实验室集中在拉曼光谱和材料的微量分析。激光晶体和金刚石薄膜的选择作为例子说明了物理学可以应用于相关主题问题的方法。新的仪器也被用于本科生的研究项目和示范。这使学生能够研究当前材料光谱学中的概念。作为这个项目的结果，学生对光谱仪器有了更好的理解，应该成为在佛罗里达中部地区发展的大型激光和电光工业的高就业率。

Modern molecular spectroscopy and micro-analysis experiments recently developed at UCF (Am. J. Phys. 62, 429-434 (1994)) will be introduced into the intermediate and advanced undergraduate laboratories. Undergraduate students are learning skills such as materials characterization by micro-Raman spectroscopy which will give them useful knowledge in preparing them for graduate school or entering the job market. They are taking advantage of the technological revolution that has taken place in this field during the past decade making small, low-cost, high-throughput instruments possible. These experiments fit very well into the undergraduate curriculum since they allow the students to investigate basic physics phenomena as well as many useful applications. The laboratory is equipped with a Raman spectrometer employing solid state laser excitation and a microscope attachment. In the intermediate lab the students have hands-on experience with absorption, emission and fluorescence using multichannel detection. Experiments in the advanced laboratory focus on Raman spectroscopy and microanalysis of materials. The choice of laser crystals and diamond films as examples illustrate ways that physics can be applied to relevant topical issues. The new instrumentation are also being used in undergraduate research projects and demonstrations. This allows students to investigate concepts in current materials spectroscopy. As a result of this program students have an improved understanding of spectroscopic instrumentation and should become highly employable in the large laser and electro-optics industry that is evolving in the Central Florida region.
