Laser Ablation Technique

Silicon nanoparticles with the size from 50 nm to 300 nm depending on used targets were formed by the picosecond laser ablation technique of porous silicon and silicon microparticles in water. Raman spectra analysis of the produced nanoparticles revealed a slight presence of the amorphous phase (10 – 12%) in them for the case of ablation of micro- and mesoporous silicon layers and almost complete crystallinity as a result of laser fragmentation of the silicon micropowders in water. The results can be helpful for further use of the considered nanoparticles in applications of photonics and biomedicine.
