The paper demonstrates that the laser ablation approach can be used for the synthesis (with average nanoparticle size control) of silicon nanoparticles supporting strong resonant optical responses in the visible spectral range. The addition of gold nanoparticles amplificates the luminescence and increases its diapason. Monolithic crystalline silicon targets are considered. The generated colloidal solutions have been used for the formation of one-layered covering composed of silicon nanoparticles. The obtained results may be used for the realization of many functional metasurfaces consisting of randomly distributed resonant nanoparticles.
