An experiment designed to connect quantum mechanical textbook examples and concepts in optics with technologically important materials is being undertaken in the upper-level undergraduate student laboratories. Using a versatile spectrometer system and an efficient detector, students are performing photoluminescence (optical emission), optical reflectivity, and Raman (inelastic scattering of light) measurements on novel materials. Samples chosen for this laboratory experiment are semiconductor quantum well heterostructures (QWH), which are used in lasers and modern electronic devices; and C60, which has potential applicatimns in several industries. The experiment on QWH is unique in connecting a real physical system with the one-dimensional square well potentials treated in elementary Quantum Mechanics or Modern Physics courses. Similarly, the experiment on C60 serves to illustrate rudiments of optical spectroscopy and its use in the characterization of new materials. These experiments modernize the undergraduate curriculum and give the students a feel for frontier research in new materials. The equipment has a long life span and is adaptable for experiments on a wide variety of materials. The project includes the use of the new equipment in two undergraduate laboratory courses and also for undergraduate student research projects. Details of the experiments and student experiences will be shared with interested colleagues at other institutions through workshops, presentations at meetings and publications in journals - American Journal of Physics and others.

一项旨在将光学中的量子力学教科书示例和概念与具有重要技术意义的材料联系起来的实验正在高水平的本科生实验室进行。使用多功能光谱仪系统和高效探测器，学生们正在对新材料进行光致发光(光发射)、光反射率和拉曼(光的非弹性散射)测量。本实验室选择的样品是用于激光器和现代电子器件的半导体量子阱异质结(QWH)和在几个行业具有潜在应用的C60。QWH实验在将一个真实的物理系统与基础量子力学或现代物理课程中讨论的一维方势能联系起来方面是独一无二的。同样，在C60上的实验有助于说明光学光谱学的基本原理及其在新材料表征中的应用。这些实验使本科课程现代化，让学生感受到新材料的前沿研究。该设备寿命长，适用于多种材料的实验。该项目包括在两门本科实验室课程中使用新设备，以及在本科生研究项目中使用新设备。实验的细节和学生经验将通过研讨会、在会议上的演讲和在美国物理杂志等期刊上发表的文章，与其他机构的感兴趣的同事分享。
