Nicholas,
Iodine (and all of the halogens) produce excimers (excited dimers) with
the noble gases. Excimers do produce unusual colored discharges, but
they have a problem -- there is nothing more chemically reactive than an
ionized halogen.
Tubes containing metal electrodes and a halogen "clean up" rapidly, as
the ionized halogens react with and permanently bind to the metal
electrodes. After a relatively short period of operation the halogens
are depleted.
Some plasma sculptures are made with halogens, and do produce
interesting colored displays, but the halogens will even attack the
silicon dioxide of the glass envelopes, and clean up after some period
of operation. I've seen a traffic light red plasma globe that used neon
plus a halogen, as well as a lovely turquoise globe that used a halogen
plus one of the heavier noble gases Neither had a long lifetime.

I wonder if anyone ever tried adding a few iodine crystals to a nixie? I know
it’s added to some plasma tubes to give a certain plasma color (i have
one....nice blue tinge to the plasma glow)....
Hmm....
