Laser-driven aluminum oxide nanoparticle synthesis for high-performance fiber optic gas sensing

This manuscript presents a novel method for the transformation of bulk aluminium metal powder into aluminium oxide nanoparticles in a liquid medium using pulsed laser irradiation. The process demonstrates high precision and control over the oxide formation, resulting in the production of nanostructured aluminium oxide particles. The synthesized material exhibits promising properties for applications in clad-modified fiber optic gas sensing due to its enhanced surface area, breakdown in particle size dimension and improved gas adsorption capabilities. The methodology outlined in this study provides a viable pathway for the development of advanced sensing materials with improved performance characteristics.
