Re: green plasma globe

Platinum wires coated with selenium when arced show very strong green lines. There are also various compounds (esp. volatile organics) that show band rather than line spectra in the green range.

(cf. "An Introduction to the Study of Spectrum Analysis" W. M. Watts, Longmans, Green & Co 1904)

Hope this helps,

I've looked for spectral emission charts for the rare gas isotopes without
much success. Perhaps some one on the list might point out a place where
the spectra could be found. If you found an isotope with strong lines in
the green, that might be your candidate for the green globe.
