金属纳米粒子的制备及光学性质探究与表面增强拉曼应用
Preparation and Optical Properties Investigation of Metal Nanoparticles for Surface-Enhanced Raman Spectroscopy
摘要
Abstract
This experiment is designed to explore the optical properties of metal nanoparticles and their applications in surface-enhanced Raman spectroscopy(SERS).It covers the synthesis,characterization,and applications of metal nanomaterials,allowing students to learn inorganic synthesis techniques and optical characterization methods while gaining insight into the experimental workflow of material preparation,property characterization,and system application-core elements of current scientific research.This experiment is suitable for students at various stages of their studies.Specifically,students will synthesize metal nanoparticles with varying sizes and shapes by adjusting the synthesis conditions at fist.Then they will characterize the optical properties and morphology using UV-Vis absorption spectroscopy and scanning electron microscopy(SEM),helping them relate these observations to basic nanophotonics principles.Finally,through the application of SERS,students will learn how preparation and characterization steps can be optimized to enhance detection results.This stepwise learning approach not only deepens students'understanding of professional knowledge but also fosters scientific thinking.关键词
