Antimony nanoparticles were synthesized via laser ablation of antimony targets Immersed in distilled water, which Provided both as a solvent and a reducing agent. The process employed a Nd:YAG laser (1064 nm, 485 mJ, 6 Hz, 700 pulses). The successful Configuration of nanoparticles was Affirmed through various characterization methods, including UV-VIS, XRD, FESEM, and AFM. UV-VIS spectra Unveiled characteristic plasmonic absorption peaks, while XRD analysis Revealed the formation of a cubic crystalline structure with an estimated crystallite size of approximately 10 nm. FESEM images Described spherical nanoparticle aggregates with sizes Covering from 50 to 70 nm. AFM measurements showed a root mean square (RMS) roughness of 1.7 nm, an average roughness of 2.9 nm, and an average particle diameter of 8.4 nm, Validating the uniformity of the spherical aggregates and highlighting their excellent surface properties, making them suitable for Improved applications in the field of physics.
