In plasma, gas atoms are excited to higher energy states and also ionized. As the atoms and molecules 'relax' to their normal, lower energy states they release a photon of light, this results in the characteristic “glow” or light associated with plasma. Different gases give different colors. For example, oxygen plasma emits a light blue color. WebThe plasma treatment of a PDMS surface with oxygen plasma can also improve the biocompatibility of the substrate. Microelectronics: PDMS in combination with plasma surface treatment (plasma cleaning, surface activation or deposition) is frequently used to either deposit PDMS on microchip substrates or to coat PDMS substrates with other … joe burrow bengals clip art
