Surface-enhanced Raman spectroscopy (SERS) is an ultrasensitive surface analysis technique that widely used in chemical sensing, bioanalysis, and environmental monitoring. The design of the SERS substrates crucial for obtaining high-quality signals. Recently, 2D transition metal dichalcogenides (2D TMDs) have emerged as high-performance due to their superior stability, ease fabrication, biocompatibility, controllable doping, tunable bandgaps excitons. In this review, a systematic overview...
The chemical mechanism (CM) of surface-enhanced Raman scattering (SERS) has been recognized as a decent approach to mildly amplify scattering. However, the insufficient charge transfer (CT) between SERS substrate and molecules always results in unsatisfying enhancement, exerting substantial restriction for CM-based SERS. In principle, CT is dominated by coupling energy levels semiconductor-molecule system laser wavelength, whereas precise tuning intrinsically difficult. Herein,...
Noncontact optical sensing plays an important role in various applications, for example, motion tracking, pilotless automobile, precision machining, and laser radars. A device with features of high resolution, fast response, safe detection (operation wavelength at infrared (IR)) is highly desired such applications. Here, a near IR position-sensitive detector constructed by graphene-Ge Schottky heterojunction has been demonstrated. The shows responsivity (minimum detectable power ∼10 nW),...

The corrosion resistance of the waterborne epoxy coating is poor during long-term service, which greatly limits its widespread application. In this paper, halloysite nanotubes (HNTs) were modified by polyaniline (PANI) and then used as nanocontainers to encapsulate green inhibitor praseodymium (III) cations (Pr3+), obtaining HNTs@PANI@Pr3+ nanoparticles. A scanning electron microscope, transmission microscopy, energy dispersive spectroscopy, Fourier transform infrared X-ray diffraction,...

Abstract Semiconducting surface‐enhanced Raman scattering (SERS) materials have attracted tremendous attention for their good signal uniformity, chemical stability, and biocompatibility. Here, a new concept to design high sensitivity semiconducting SERS substrates through integration of both amorphous nonstoichiometric features WO 3− x thin films is presented.
