Transition metal dichalcogenide nanospheres for high-refractive-index nanophotonics and biomedical theranostics.

ABSTRACT: Recent developments in the area of resonant dielectric nanostructures have created attractive opportunities for concentrating and manipulating light at the nanoscale and the establishment of the new exciting field of all-dielectric nanophotonics. Transition metal dichalcogenides (TMDCs) with nanopatterned surfaces are especially promising for these tasks. Still, the fabrication of these structures requires sophisticated lithographic processes, drastically complicating application prospects. To bridge this gap and broaden the application scope of TMDC nanomaterials, we report here femtosecond laser-ablative fabrication of water-dispersed spherical TMDC (MoS₂ and WS₂) nanoparticles (NPs) of variable size (5 to 250 nm). Such NPs demonstrate exciting optical and electroni
