This section GB/T 24369 specifies the gold nanorods UV/VIS/NIR absorption spectra and characterization methods used to gauge the absorption peak
Operators average axial ratio.
This section applies to the axis ratio of 2 to 5, a cylindrical rod of gold 30nm diameter less than characterization.
Other precious metals nanostructures UV/VIS/NIR absorption spectra characterization may also refer to the implementation of this section.
