Glow Discharge - an overview | ScienceDirect Topics
Glow discharge is characterised as a uniform, homogeneous and stable discharge usually generated in helium or argon (and some in nitrogen). This is done, for example, by applying radio frequency voltage across two parallel-plate electrodes.
Glow Discharge: Its Use in Transmission Electron Microscopy (TEM)
Glow discharge is used to alter wetting properties of surfaces and make the charge of the surface uniform. This helps in homogenous dispersion of the sample on the surface and can also direct orientation of molecules on the support. What are some of the factors to consider when working with glow discharge?

1999年9月1日 · The use of the glow discharge for analytical chemistry is based material; the electrons can, in turn, give rise to new ionization on the principle of ‘sputtering’.

Glow discharge is the formation of a plasma by the electrical breakdown of a gas. Normally, gases are insulators. Because of cosmic rays or other natural background radiation, a volume of gas contains a few randomly generated electrons.
Glow Discharge - an overview | ScienceDirect Topics
Glow discharge is a transitional discharge that exists between corona and spark, characterized by large discharge volumes, high electron densities, and good energy efficiency.
Glow Discharge - an overview | ScienceDirect Topics
The glow discharge (see Fig. 2) is a low energy plasma ion source that works at a low pressure of 0.1–10 Torr (mostly using argon as the plasma gas). The Ar + ions formed in the glow discharge are accelerated toward the sample cathode and the sample material is sputtered at the cathode surface by ion bombardment. Sputtered atoms and molecules ...

2022年6月9日 · How Does Glow Discharge Optical Emission Spectrometry Work? Glow discharge is plasma that forms when an electric current is passed through a gas. It is produced when voltage is applied between a cathode and an anode in a glass tube containing a low-pressure gas like helium.
glow discharge (also called a gas discharge) is probably the most simple plasma generation technique used in vacuum coating.1 The plasma thus generated is used as a source of high-energy ions for sputtering and ion plating (“atomic peening”). The primary glow discharge properties of concern in these applications are the particle species ...
By their nature, GD sources provide means of converting solid specimens into gas-phase atoms and molecules in a controlled fashion. This quality is, of course, the basis of the still-growing use of glow discharge sources in bulk solids and depth-resolved elemental analysis.
