本文报道了一种基本现象，即通过静态或喷射流的液态金属电极，可以在低电压下在水溶液中轻松触发放电等离子体。产生带有光发射的等离子体，每次可以持续几毫秒，但具有一致的电流。这种发射光谱的主峰位于蓝色、紫色和紫外部分，主要是由镓和铟的等离子体引起的。还研究了电压方向和溶液成分等条件变化对此现象的影响。此外，这种产生等离子体的方法也被证明可用于制造微米级金属颗粒或其他化合物。
This paper reports a fundamental phenomenon whereby discharge plasma can be easily triggered in aqueous solution under a low voltage via a liquid metal electrode that is either static or a jetting stream. Plasmas with light emission are generated, which could last for several milliseconds each time, yet with a consistent current. The principal peaks of such optical emission spectrum lie in the blue, violet and ultraviolet sections, which are mainly caused by the plasma of gallium and indium. The influence of condition changes, such as voltage direction and solution constituents, on this phenomenon was also investigated. Further, this method to produce plasma has also been demonstrated to be useful for the fabrication of micro-sized metal particles or other compounds.
