| glow discharge | <radiobiology> Low-density, low-temperature plasma discharge (such as in a fluorescent light) which, well, glows. Sputtering in glow discharges is useful in plasma processing of materials. The voltage applied to the plasma must be greater than the ionisation potential of the gas used, most of the plasma voltage drop is near the cathode, where the majority of ionisation occurs. Discharge is sustained by secondary electrons emitted when ions or recombination radiation impact on the cathode, electrons are accelerated away from the cathode and ionize neutral gas in the discharge.

| glowworm | <zoology> A coleopterous insect of the genus Lampyris; especially, the wingless females and larvae of the two European species (L. Noctiluca, and L. Splendidula), which emit light from some of the abdominal segments. "Like a glowworm in the night, The which hath fire in darkness, none in light." (Shak) The male is winged, and is supposed to be attracted by the light of the female. In America, the luminous larvae of several species of fireflies and fire beetles are called glowworms. Both sexes of these are winged when mature. See Firefly. Source: Websters Dictionary (01 Mar 1998) |
