I-V characteristics and the synthesis of ZnS nanoparticles by glow discharge at the metal-ionic liquid interface

A plasma chamber was constructed for the synthesis of ZnS nanoparticles in ionic liquid by glow discharge electrolysis method. Current and voltage (I-V) characteristics of the discharge at the metal-ionic liquid interface showed that the curve follows Ohm's law up to a particular voltage only so that the ZnS nanoparticle preparation was performed after the critical voltage. X-ray diffraction and energy dispersive spectral analysis showed that the samples contain ZnS nanoparticles and also found that tungsten from the metal electrode dissolved in the BMIM[BF₄] ionic liquid under plasma and formed tungstic oxide by accepting atmospheric oxygen.
