Transition metal oxide semiconductors have been explored in surface-enhanced Raman scattering (SERS) active substrates, yet their detection sensitivity and enhancement effects are inferior. What’s more, the reported fabrication technique ignored the effects of the electromagnetic mechanisms and was far from satisfactory for practical applications. Herein, we report on a convenient nanotechnique to fabricate large-area hexagon plum-blossom-like WO3-x nanoarrays based on aluminum nanobowl array substrates. Localized surface plasmon resonance can be increased via adjusting the time of tungsten magnetron sputtering with H2 annealing treatment. The introduction of a double-switch experiment demonstrates that localized surface plasmon-coupled photoinduced charge transfer can not only increase SERS enhancement comparable to similar silver nanostructures but also implement a low limit of detection below 10-9 M. A triple-switch experiment offers specific rules in the mol. detection of WO3-x semiconductors and important guidance for the fabrication of SERS-active semiconducting platforms.
After consulting a lot of data, we found that this compound(4556-23-4)Quality Control of Pyridine-4-thiol can be used in many types of reactions. And in most cases, this compound has more advantages.
