| 1 | Dual-step hybrid SERS scheme through the blending of CV and MoS_(2) NPs on the AuPt core-shell hybrid NPs显示文摘Along with a wide range of applications,the surface-enhanced Raman spectroscopy(SERS)is a promi-nent analytical technique to recognize and detect molecules and materials even at an extremely low mo-lar concentration.In this work,a unique hybrid SERS platform is demonstrated by the incorporation of molybdenum disulfate(MoS_(2))nanoparticles(NPs)onto the core-shell AuPt hybrid NPs(HNPs)for the en-hanced molecular Raman vibration of crystal violet(CV).The hybrid platform takes the advantage of both the electromagnetic mechanism(EM)offered by the AuPt HNPs and chemical mechanism(CM)owing to the MoS_(2)NPs.The distinctive core-shell morphology of AuPt HNPs with the high-density background Au NPs is attained by a unique two-step solid-state dewetting method,which can offer a high concentration of electromagnetic hot spots.At the same time,the MoS_(2)NPs can provide an ample charge transfer with abundant active sites.Through the hybrid SERS approach,a dramatic SERS enhancement of CV Raman vibration is demonstrated,and the SERS capability is thoroughly studied.In addition,the finite-difference time-domain(FDTD)simulations provide a deeper understanding of the electromagnetic field distributions for various configurations of nanostructures and their hybrid combinations:i.e.,HNPs,alloy NPs,MoS_(2)/HNPs configurations. | Rutuja Mandavkar Shusen Lin Rakesh Kulkarni Sanchaya Pandit Shalmali Burse Md Ahasan Habib Puran Pandey Sundar Kunwar Jihoon Lee | 2022 | Journal of Materials Science & Technology2022，，12： | 0 |
