Tha absorption spectrum is the negative of the emissinon spectrum as far I remember.

All you need is a good source of high energy photons to initiate ionisation... Ordinary common high-intensity blue LEDs seem to work well. One thing that might be worth trying is finding an LED that emits photons in one of the neon absorption bands. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
