I don't think you need barium oxide or the like for emission, but I do seem to recall that nixies generally have something coated on the back of the digits to suppress the discharge there, to concentrate it on the fronts. I had been toying with this too, but had trouble sourcing insulators for the digit stack. http://www.vitriol.com/images/tech/nixies/cathodes.gif - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
