【交流】temperature dependence of Au surface plasmon resonance
|
|||
| Au nanoparticles has surface plasmon resonance near 510nm (Ag nanoparticles near 420nm). the physics origin of this resonance is due to charge oscillation (which is different from semiconductor bandgap). does anyone know if this peak position will shift with temperature? Say, if the nanoparticle is cooled to the liquid nitrogen or liquid helium temperatures, will the surface plasmon resonance peak remain the same?? |
