Plasma polymers can be thought of as a type of graft polymer since they are grown off of a substrate. These polymers are known to form nearly uniform surface deposition, which is one of their desirable properties. Polymers formed from this process often cross-link and form branches due to the multiple propagating species present in the plasma.
Aerolux Light Corporation was a manufacturer of artful gas-discharge light bulbs from the 1930s through the 1970s. [1] Aerolux made these bulbs in a factory in New York City . US Patents dating back to the 1930s describe the design and construction of these bulbs.
Glow-discharge optical emission spectroscopy (GDOES) is a spectroscopic method for the quantitative analysis of metals and other non-metallic solids. The idea was published and patented in 1968 by Werner Grimm from Hanau, Germany .
Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer. Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber. Its chief advantage over the glass product, other aspect being equal, is its robustness under bending and stretching.
These particles excite the phosphor, causing it to emit a low, steady glow. Tritium is not the only material that can be used for self-powered lighting. Radium was used to make self-luminous paint from the early 20th century to about 1970. Promethium briefly replaced radium as a radiation source. Tritium is the only radiation source used in ...
The A-D region is called a dark discharge; there is some ionization, but the current is below 10 microamperes and there is no significant amount of radiation produced. The F-H region is a region of glow discharge; the plasma emits a faint glow that occupies almost all the volume of the tube; most of the light is emitted by excited neutral atoms.
H: abnormal glow discharge I: unstable region: glow-arc transition J: electric arc K: electric arc A-D region: dark discharge; ionisation occurs, current below 10 microamps. F-H region: glow discharge; the plasma emits a faint glow. I-K region: arc discharge; large amounts of radiation produced. A Townsend discharge can be sustained only over a ...
A plasma afterglow (also afterglow) is the radiation emitted from a plasma after the source of ionization is removed. [1] The external electromagnetic fields that sustained the plasma glow are absent or insufficient to maintain the discharge in the afterglow.
