Enhancement of third-order optical nonlinearity of VSe₂ by hybridizing with CoSe₂ as flower-like nanoparticles.

ABSTRACT: Through one-pot hydrothermal synthesis, we synthesized VSe₂-CoSe₂ nanostructures with a distinctive flower-like morphology. The structural characterizations were conducted using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and Fourier transform infrared spectroscopy (FTIR). By modulating the proportion of the CoSe₂ phase, we transformed these hybrid nanostructures into nanoparticles, thereby influencing their nonlinear optical properties. The third-order nonlinear optical parameters (n ₂ and β) were rigorously examined via the precise Z-scan technique under various laser power conditions. The nanostructures demonstrated a self-focusing refractive response and exhibited pronounced two-photon ab
