Resonant Optical Properties of Crystalline Silicon Nanoparticles Fabricated by Laser Ablation-based Methods

摘要

In this work we demonstrate resonant Raman scattering from crystalline silicon nanoparticles, fabriacted using a single-stage fabrication process based on femtosecond laser ablation. Experimental and analtyical modelling shows 140-times enhancement of Raman scattering from Resonant nanoparticles, relative to their nonresonant counterparts.
