| 摘 要： | 本文用衰减全反射(ATR)和光声(PA)方法研究表而等离子激元(surface plasmons)的衰减,分别对Ag-空气界面和CaF_2-Ag-空气界面进行衰减全反射谱和光声光谱测定.测量结果确定两种衰减方式,辐射和无辐射定量结果,并且发现表面粗糙度对衰减方式有影响.

| Abstract: | Photoacoustic (PA) observation of the decay channels of surface plasmons wag made on the plasmong excited by the attenuated total reflection (ATE). Both in the interfaces of Ag-air and CaF2-Ag-air, ATR and PA spectrum were measured at the game time. The results show that it is possible to determine the radiative and non-radiative decay quantatively by comparing measurements taken with transparent and blackened cavities. |
