In this paper, we report production of colloidal brass particles by pulsed laser ablation in deionized water in the presence of external electric field (EEF). The colloidal brass particles have sizes ranging from nano-scale to submicron sizes. The ablation rate and particles production yield in the presence of EEF was studied. The paper also presents the results of investigations on surface plasmon resonance (SPR), and size distributions of particles. These investigations show that EEF influences the ablation process and increases the particle concentrations. According to results, applying EEF leads to rise of nanoparticles (NPs) yield and decrease of their average size. According to our results, a blue shift occurs for SPR when EEF is applied.

在本文中，我们报告了在存在外部电场（EEF）的情况下，在去离子水中通过脉冲激光烧蚀产生的黄铜胶体颗粒。胶体黄铜颗粒的尺寸范围从纳米级到亚微米级。研究了在EEF存在下的烧蚀速率和颗粒产量。本文还介绍了表面等离振子共振（SPR）和颗粒尺寸分布的研究结果。这些研究表明，EEF影响消融过程并增加了颗粒浓度。根据结果​​，应用EEF会导致纳米颗粒（NPs）产量增加​​和平均尺寸减小。根据我们的结果，当应用EEF时，SPR发生蓝移。
