An atmospheric-pressure plasma sustained by an ac power supply was generated using electrolyte solution as one of the electrodes. By altering the power supply, ring-like patterns, double-ring patterns and plasma-spot patterns were observed at the electrolyte–electrode surface. Synchronous current–voltage characteristics and time-resolved images were measured. Important factors for the self-organized patterns, including the electrode gap, power, frequency and electrolyte concentration, were explored. The optical spectrum characteristics of the device were investigated. The pH of the solution after discharge was also explored and the results show that the pH of the solution is evidently reduced after the discharge, implying that acidic components are produced in the solution. This study provides an alternative discharge method for producing patterns on a water surface.
