Abstract The objective of this study was to design a versatile and reusable pesticide detection surface-enhanced Raman scattering (SERS) substrate in combination with SERS enhancement and self-cleaning properties. In this paper, we present an inexpensive way to synthesize three-dimensional tilted ZnO micron rods with an Ag hierarchical structure (ZMRs/Ag arrays). Although expensive materials and complex methods were not used, the detection limit of thiram residue was 10-11 M, with a quantitative...

We report on the fabrication of neodymium doped zinc oxide (ZNO) for use in surface-enhanced Raman spectroscopy (SERS). The SERS enhancement of ZNO nanoparticles exhibited 7 times higher than that of pure zinc oxide. We analyzed in detail the enhancement mechanism of the ZNO. The detection limit of malachite green (MG) was 10−7 M, and the SERS signal intensity showed a good linear relationship with the logarithm of the MG concentration (R2 = 0.9817). This indicates that ZNO is an excellent SERS ...

A commercial SERS substrate does not only require strong enhancement, but also can be reused and recycled in actual application. Herein, Fe3O4/SiO2/ZnO/Ag (FSZA) have been synthesised, which consisted of Fe3O4 core with strong magnetic field response and an intermediate SiO2 layer as an electronic barrier to keep the stability of magnetite particles and outer ZnO and Ag as the effective layers for detecting pollutants. The SERS enhancement factor (EF) of the FSZA was ~8.2 × 105. The enhancement ...

A heterojunction microcomposite was synthesized that consists of ZnO nanoparticles (ZnO NPs) anchored on MoS2 microflowers (MoS2 MFs). The material is shown to enable trace level detection of the pollutant bisphenol A (BPA). The microcomposite was characterized by XRD, XPS, SEM and TEM. In addition, coupling reaction between phenolic estrogens and Pauly’s reagents was adopted to greatly enhance the SERS signal. BPA display a characteristic Raman band at 1592 cm−1 which can be used for its select...

Here, we develop a new method to improve the surface-enhanced Raman spectroscopy (SERS) activity of ZnO using Mg doping combined with noble metals. Highly aligned silver nanoparticles (AgNPs) decorated on an array of Mg-doped ZnO (MZO@Ag) were fabricated. Using rhodamine 6G as the probe molecule, SERS indicated that the MZO@Ag substrate possesses perfect sensitivity, homogeneity, and chemical stability. The enhancement mechanism of this substrate was analyzed in detail, and finite-difference tim...

Compared with noble metals, semiconductors have been gradually exploited more as another type of SERS substrate materials due to their distinctive advantages. However, an inferior enhancement factor (EF) is a fatal weakness of the semiconductors. So, we combined the strong LSPR coupling between Ag particles and the charge transport channels induced by Mg doping to create a high performance SERS substrate. These magnesium-doped zinc oxide–Ag nanoparticles (ZMOA) exhibited 18 times higher SERS enh...

Abstract A novel white-emitting ZnO@Eu2O3 core/shell nanomaterials was synthesized by a green chemical method. The temperature and pressure dependence of the photoluminescence (PL) transition associated with the fundamental bandgap of ZnO@Eu2O3 core/shell nanomaterials have been studied. The activation energy of ZnO@Eu2O3 is 0.27 eV, which is higher than the commercial Y2O3: Eu 3+. The near-bandedge emission is found to shift toward higher energy with applied pressure at a rate of 32.7 MeV/GPa w...

Abstract The structural, optical properties and catalytic activity of ZnO@Eu 2 O 3 core-shell nanostructutres have been investigated systematically. Sharp intense red emissions in the range of 580–650 nm due to the intra-4f transition of Eu 3+ ions are observed from the sample. It is found that some of the Eu 3+ ions are in the Eu 2 O 3 -like state located at the surface of ZnO and others are doped into ZnO host. Incorporation of Eu 3+ ions into a ZnO host resulted in deterioration in crystal qu...
