摘 要：Surface-enhanced Raman scattering(SERS)and photoluminescence(PL)are important photoexcitation spectroscopy techniques;however,understanding how to analyze and modulate the relationship between SERS and PL is rather important for enhancing SERS,having a great effect on practical *** this work,a charge-transfer(CT)mechanism is proposed to investigate the change and relationships between SERS and *** the change in PL and SERS before and after the adsorption of the probe molecules on Nd-doped ZnO indicates that the unique optical characteristics of Nd^(3+) ions increase the SERS *** the other hand,the observed SERS can be used to explain the cause of PL background *** study demonstrates that modulating the interaction between the probe molecules and the substrate can not only enhance Raman scattering but also reduce the SERS *** work also provides a guideline for the investigation of CT as well as a new method for exploring fluorescence quenching.
