“…In addition, the crystallinity in Si nanoparticles has been an advantage for potential biomedical applications such as in drug delivery, imaging [8]. To date, various research groups have reported on the fabrication of Si NPs using different methods/techniques such as chemical vapour deposition (CVD) [9], radiofrequency sputtering [10], electrochemical etching [11], laser ablation [12][13], and so on. The advantage of employing individual methods is varied from one to the other.…”

We report on the ultrafast (femtosecond) laser ablation of monocrystalline Si (100), polycrystalline Si, and Si (100) capped with a SiO2 layer. The target material was ablated using femtosecond laser pulses (~50 fs duration, 1 kHz repetition rate, and 800 nm wavelength) with an input energy of ~100 μJ in acetone medium to fabricate Si Nanoparticles (NPs). The average size of NPs produced by Si (100) was found to be less than that of the particles produced by poly Si. Ablation of Si caped with SiO2 resulted in bigger Si NPs together with a low concentration of SiO2 NPs. NPs were found to be of polycrystalline in all three cases irrespective of the initial phase.
