introduction
Since the novel nature of the scale effect brought about nanomaterials gives more functionality. Anisotropic nanocrystalline noble metal is one
one type. Nanoscale noble metal nanocrystals with strong surface plasmon resonance characteristics. This feature not only scale-dependent resonance,
Its shape is also closely related. Precious metal nanocrystals surface plasmon resonance peaks and the peak position and the number of surface-enhanced Raman scattering has
Efficient spectral range can be performed by controlling the shape control and optimization. Therefore, they are more excellent than the spherical particles of some of the optical
And electrical properties.
Excellent performance is expected in the noble metal nanostructures biosensors, drug delivery, disease diagnosis and treatment, biological and biomedical imaging
Closely related fields play an important role. These properties are most closely associated with the surface characteristics of plasma. Therefore, in order to better
Use of these properties, to characterize the features of the surface plasmon becomes extremely important. Typically, a noble metal nanostructure surface ion
