Abstract

This work is dedicated to laser engineering of spherical resonant Mie-excitonic nanoparticles from layered materials, particularly Transition Metal Dichalcogenides (TMDC). The proposed approach leverages femtosecond laser ablation and fragmentation in liquids for the fabrication of water-dispersed ultra-stable spherical TMDC nanoparticles (NPs) of variable size (5 – 250 nm). Such nanoparticles demonstrate exciting optical and electronic properties inherited from the TMDC crystals, due to preserved crystalline structure, which offers a unique combination of pronounced excitonic response and high refractive index value, making possible a strong concentration of electromagnetic field in nanoparticles.
