纳米谱学分析相关产品推荐-百灵威

纳米谱学分析是探究纳米体系的关键手段。

它涵盖多种常用谱学方法，像光学光谱中的紫外可见、红外、拉曼光谱，还有电子能谱如X 射线光电子能谱（XPS）、紫外光电子能谱（UPS）、俄歇电子能谱（AES）等，能从不同角度剖析纳米材料结构与性能，具有高分辨率、非破坏性等特点，广泛应用于材料、能源、生物医学、环境等领域，为纳米材料合成、能源研究、药物研发、环境监测治理等提供依据。

一、 紫外可见光光谱

紫外分光光度计是实现紫外可见光光谱分析的工具，同时也是分析纳米颗粒的一种重要手段。利用紫外可见分光光度计，将纳米颗粒制成溶液或胶体放入比色皿测量，原理是光照射使纳米颗粒电子跃迁产生吸收峰。据此能分析粒径，如金纳米颗粒粒径变化会使吸收峰红移；成分，不同元素组成有特征吸收谱；结构，晶体、形貌不同光谱有差异；稳定性，监测光谱变化可知其稳定性。操作简便、能测多种信息，但存在光谱重叠、难获单个颗粒详情及检测灵敏度有限等局限。

百灵威可提供多种紫外分光光度计测试用试剂，产品详情如下：
