چکیده
In this work, we present a study on the sensing of chemical molecules with Au nanoparticles coated ZnO film by employing photo-induced enhanced Raman scattering (PIERS) coupled to surface-enhanced (SERS). Moreover, interest coupling PIERS classical SERS (electromagnetic contribution) is achieve high sensitivity detection. our employed thiophenol molecule for its quality adsorption metals and small size. For detection, found limit concentration 100 pM, an capacity (KAds) 3.2 × 106 M−1 analytical enhancement factor 1.9 1010.

UV sensing using film bulk acoustic resonators based on Au/n-ZnO/piezoelectric-ZnO/Al structure
A new type of ultraviolet (UV) light sensor based on film bulk acoustic wave resonator (FBAR) is proposed. The new sensor uses gold and a thin n-type ZnO layer deposited on the top of piezoelectric layer of FBAR to form a Schottky barrier. The Schottky barrier's capacitance can be changed with UV light, resulting in an enhanced shift in the entire FBAR's resonant frequency. The fabricated UV se...
متن کاملA rapid SERS method for label-free bacteria detection using polyethylenimine-modified Au-coated magnetic microspheres and Au@Ag nanoparticles.
A rapid, sensitive, and label-free SERS detection method for bacteria pathogens is reported for the first time. The method, which is based on the combination of polyethylenimine (PEI)-modified Au-coated magnetic microspheres (Fe3O4@Au@PEI) and concentrated Au@Ag nanoparticles (NPs), was named the capture-enrichment-enhancement (CEE) three-step method. A novel Fe3O4@Au microsphere with monodispe...
متن کاملReview of SERS Substrates for Chemical Sensing
The SERS effect was initially discovered in the 1970s. Early research focused on understanding the phenomenon and increasing enhancement to achieve single molecule detection. From the mid-1980s to early 1990s, research started to move away from obtaining a fundamental understanding of the phenomenon to the exploration of analytical applications. At the same time, significant developments occurr...
متن کاملCharacterization of nanostructured SnO2 thin film coated by Ag nanoparticles
Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...
متن کاملAnchoring Au Nanoparticles onto ZnO Nanowires by Heteroepitaxy
Supported Au nanoparticles (NPs) with sizes < 5 nm have been proved to be highly active for many important catalytic reactions [1]. The development of thermally stable supported Au NP catalysts, however, is challenging. Unlike other noble metals, Au NPs or clusters sinter rapidly during catalytic reactions at elevated temperatures or even under long-term storage [2]. There are many approaches t...
