样品退火后，表面等离子体共振吸收峰红移，而伴峰消失。
After annealing, the peak attributed by the SPR shifts to red and the other peak disappears.
此外，合适的激发光，能更好地匹配金属衬底的表面等离子体共振吸收，对表面增强荧光效应更加有利。
It is also found that proper excitation wavelength, which corresponds to greater SPR absorption of metal substrate, is another factor that can significantly influence the SEF effect.
研究表明，银的等离子体共振吸收峰的移动是尺寸效应和表面效应共同作用的结果。
The shift in absorption spectra of the silver plasmon band is explained in terms of surface effects and size effects.
