Synthesis and characterization of Fe₂O₃ nanoparticles via pulsed laser ablation in liquids: effects of solvent and laser fluence.

ABSTRACT: In this study, the synthesis and characterization of iron (III) oxide (Fe₂O₃) nanoparticles using the pulsed laser ablation in liquids (PLAL) technique are reported. A 1064 nm Nd: YAG laser was used to ablate a hematite target immersed in different liquid media (acetone, ethanol, isopropanol, and bi-distilled water) under two distinct laser fluences (0.75 and 1.00 J/cm²). Fluence was varied by fixing spot size and changing the laser energy using the laser Q-switch delays, generating colloid with different stabilities within 4 min. The resulting nanoparticles were characterized by UV-Vis spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), selected area electron diffraction (SAED), and Raman spectroscopy. The UV-Vis spectra confirmed typical Fe₂O₃ ab
