摘要
随着激光技术的发展，电子俘获材料的应用研究已经扩展到了辐射剂量测定、光计算、光信息处理和光存储等许多新兴技术领域，并且对于一些特殊基质，经适当方式引入稀土激活中心制得的电子俘获材料，利用其在室温下可将红外光转换为可见光的特性，可实现在红外探测和红外上转换成像等方面的应用，如夜视系统材料、红外量子计数器、发光二极管以及其他激光材料等，在国民经济和国防建设领域有较大的应用潜力。本项目主要对电子俘获材料以及贵金属纳米颗粒的特性进行研究，首先进行贵金属纳米颗粒的合成与表征，探究其表面等离子体共振特征与其大小、形貌和周围介质的关系。然后将贵金属纳米颗粒与电子俘获材料相结合，探索贵金属纳米颗粒与电子俘获材料相互作用所产生的新的光学特性以及相关的物理机制，从而获得具有更好红外上转换特性的新型电子俘获材料。本文主要内容包括贵金属纳米颗粒的制备，二氧化硅包覆的新方法，贵金属纳米颗粒与电子俘获材料的结合方法以及结合后新材料有关特性的研究结果。
