摘要
激光产生的等离子体中的气相氧化受等离子体内部和周围氧气供应情况的显著影响。在本研究中，我们研究了在空气和氩气中分别由铝（Al）和 Al2O3 靶件产生的等离子体中，靶件衍生氧和环境氧对 AlO 形成的作用。我们的研究结果表明，气相氧化发生在氩气中 Al2O3 等离子体演化的早期，这与空气中的 Al 等离子体形成了鲜明对比，在空气中，由于最初将氧气排除在等离子体之外，延迟了化学反应的发生。
Impact of target-derived and ambient oxygen on gas-phase oxidation in laser ablation plumes.
Gas-phase oxidation in a laser-produced plasma is significantly influenced by the availability of oxygen in and around the plume. In this study, we investigate the role of target-derived and ambient oxygen on AlO formation in plasmas generated from aluminum (Al) and Al2O3 targets in air and argon, respectively. Our results highlight that gas-phase oxidation occurs early during the evolution of Al2O3 plasmas in argon, in contrast to Al plasmas in air, where the initial exclusion of oxygen from the plume delays the chemical reactions.
