According to Wiki, Krypton should emit a violetish colour. I guess also UV. So maybe you have seen a krypton discharge lamp with an Uranium glass mantle. The green colour will be due to fluorescence evoked by the UV-light that excites the uranium atoms to send off green light.
@Dalibor: Beware of uranium glass it is extreme expensive, however, may be in your country it might still be made (Bohemia?). eric Van: [email protected] [mailto:[email protected]] Namens John Smith Verzonden: vrijdag 10 januari 2014 18:56 Aan: [email protected] Onderwerp: Re: [neonixie-l] Re: What to do with a 0B3 regulator tube ? Most likely Krypton gas...usually the glass is stained to enhance the green color.

I was hoping that reverse-polarity would produce more glow; no such luck. Most of the interesting glowing is hidden inside the metallic area of the tube. Even with higher current, the glow was barely affected. It's so dim that it wouldn't even make a decent night-light. Any ideas out there ? Since these aren't rare tubes (yet...), I'm tempted to repeat an experiment I did in high school with a 0A2 regulator tube: I cranked so much current thru it that the plate glowed red-hot, the glass softened and due to the vacuum, and it shrank around the metal. Watching the poor tube shrivel-up and die made me laugh so hard I cried. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
