External electric field assisted laser-induced plasma and bubble dynamics for optimizing Mn2O3 nanoparticles as UV emitters

Abstract

To gain a deeper understanding of how the size of the nanoparticles synthesized by Electric Field-Assisted Laser Ablation in Liquids (EFLAL) changes with the applied electric field, we use Laser-Induced Breakdown Spectroscopy (LIBS) and a Beam Deflection Set-up (BDS). These tools help us examine how the electric field strength affects the plasma parameters and the bubble dynamics. The findings show that the electron density and plasma temperature are perturbed as the electric field strength can alter the interaction region. The strength of the electric field can cause the bubble size to increase, which also elevates its pressure and temperature. These alterations at the breakdown region lead to changes in the size, properties, and production of the Mn₂O₃ nanoparticles. Thus, the interplay of laser plasma and fluid-assisted bubble phenomena in the presence of an electric field is probed for Mn₂O₃ nanoparticles thereby optimizing as UV emitters.
