چکیده
It is a challenging yet valuable work to prepare surface-enhanced Raman scattering (SERS) substrate with low cost and high performance by simple methods. In this study, the Ag nanoparticles were sputtered on PS spheres magnetron sputtering, which was used as mask create nanostructures etching spheres. Because of heating effect in process, gathered surfaces when time 60 s. Strong electromagnetic coupling observed between confirmed FDTD simulation SERS signals from probe molecule 4-mercaptobenzoic acid. This structure showed detection limit for thiram down 10−8 M.

متن کامل3-D aluminum nanostructure with microhole array synthesized by femtosecond laser radiation for enhanced light extinction
This article presents 3-D aluminum micro-nanostructures for enhanced light absorption. Periodic microhole arrays were created by firing a train of femtosecond laser pulses at megahertz pulse frequency onto the surface of an aluminum target at ambient conditions. The laser trains ablated the target surface and created microholes leading to the generation of deposited nanostructures inside and ar...

متن کاملCPW Fed Double T-Shaped Array Antenna with Suppressed Mutual Coupling
A compact CPW-fed double T-Shaped antenna is proposed for dual-band wireless local area network (WLAN) operations. For the proposed antenna, the -10 dB return loss bandwidth could reach about 25.5% for the 2.4 GHz band and 5.7 % for the 5 GHz band, which meet the required bandwidth specification of WLAN standard. To reduce the mutual coupling and get high isolation between two dual-band antenna...
