Laser-synthesized nanoparticles improve surface-enhanced Raman scattering and photocatalytic efficiency, suggesting a valuable application in nanotechnology.
Nanoparticles The image artistically represents the femtosecond laser-mediated fabrication of PdSe2-x nanoparticles from a bulk PdSe2 crystal. In contrast to the crystalline precursor, NPs are amorphous with higher concentration of broken chemical bonds and Selenium vacancies on the surface, which activate the NPs multiple functionalities for SERS, photocatalysis and photothermal conversion. Surface of amorphous NPs efficiently traps various dies and analytes (small crystallites in the image) and improves SERS, allegorically represented in the image via Raman spectrum. More details can be found in the Research Article by Valentyn Volkov and co-workers (DOI: 10.1002/admi.202500902).
