This project, at an RUI institution, provides undergraduate students with research experience through an active program in laser spectroscopy. Students are actively involved in the study of optical properties of rare earth ions doped in crystalline host materials, and novel organic dyes in solid plastic materials. Measurements include time-resolved spectroscopic techniques to study energy transfer characteristics and mechanisms. Processes such as energy transfer between sensitizers and activators, fluorescence quenching, Stoke's shifts, and the effect of host materials on such processes are studied. The research aims to help students understand and solidify their thinking about energy levels, selection rules, radiative and nonradiative processes. Students actively participate in weekly group discussions interacting with fellow students and the PI.%%%The project is primarily oriented toward providing research education experience for undergraduates in materials physics studies including advanced characterization tools and analysis methods to address basic research issues in a topical area with technological relevance. The research will contribute basic materials science knowledge to important aspects of processing and fabricating photonic devices such as lasers and sensors. An important feature of the program is the way in which research and education are integrated through the training of students in basic research in a technologically significant area.***

这个项目，在RUI机构，通过激光光谱学的积极计划为本科生提供研究经验。 学生们积极参与晶体主体材料中掺杂的稀土离子的光学性质以及固体塑料材料中新型有机染料的研究。 测量包括时间分辨光谱技术，以研究能量转移特性和机制。 研究了敏化剂和活化剂之间的能量转移、荧光猝灭、斯托克位移等过程以及主体材料对这些过程的影响。 该研究旨在帮助学生理解和巩固他们对能级，选择规则，辐射和非辐射过程的思考。 学生积极参与每周小组讨论，与同学和PI互动。%该项目主要面向为材料物理研究的本科生提供研究教育经验，包括先进的表征工具和分析方法，以解决具有技术相关性的主题领域的基础研究问题。该研究将为加工和制造光子器件（如激光器和传感器）的重要方面提供基础材料科学知识。该计划的一个重要特点是通过对学生进行技术重要领域的基础研究培训来整合研究和教育的方式。
