摘要: Metal–semiconductor composite microstructures have recently been demonstrated to possess potential applications due their unique structures. Ag–Cu2O (Ag–Cu2O CMSs) with tunable silver content synthesized a facile in situ method. Ag contents on the surface of Cu2O can be tuned through variation concentration AgNO3, which further greatly affected surface-enhanced (resonance) Raman scattering (SE(R)RS) performance. The CMSs prepared 0.4 mM AgNO3 show optimum SE(R)RS properties, better than pure NPs. Furthermore, enhancement mechanism and uniformity are investigated detail.
