smaller and more shape-diversified, through which a unique kind of cauliflowershaped architecture has been constructed whose branches and shrubs are formed by
clusters of smaller particles.
The light absorption properties of these four SMNS on Cu are shown in Fig. 2.33a.
Intrinsically, the polished Cu surface has strong light reflection. The reflection spectrum decreases gradually from Structure 1 to Structure 4, consistent with the changing
