Au和Ag纳米粒子表面等离子体共振频率漂移的起源

Origin of Shifts in the Surface Plasmon Resonance Frequencies for Au and Ag Nanoparticles

S. Dhara

摘要:

在贵金属(金,银)纳米团簇的表面等离子体共振(SPR)频率的变化的起源在本书的章节中进行了讨论。电子从费米面溢出被认为是红移的起源。另一方面,考虑了多孔介质中贵金属电子的屏蔽和屏蔽表面电子的量子效应,观察到的SPR峰位的蓝移。

英文摘要:

Origin of shifts in the surface plasmon resonance (SPR) frequency for noble metal (Au, Ag) nanoclusters are discussed in this book chapter. Spill out of electron from the Fermi surface is considered as the origin of red shift. On the other hand, both screening of electrons of the noble metal in porous media and quantum effect of screen surface electron are considered for the observed blue shift in the SPR peak position.
