Abstract

In this paper, pulsed discharge is used to control the luminous color in gas discharge tubes. The luminous color of the positive column in gas discharge tubes filled with Hg-Ar-Ne (1: 9, 60［Torr］) and having no phosphor material, varies from red to blue emitted by the Ne and Hg from the pulsed discharge. With changing of pulse-width and frequency, the electron temperature in the transient period affects changes to the residual ion and metastable atom densities. The first metastable atoms containing energy levels of about 16.6 ［eV］have a very high probability that a collision will result in the ionization potential of Ar being 15.8 [eV]. The change of locus in the CIE chromaticity diagram with increasing pulse-width and frequency approves the variation of luminous color.
