- I remember reading about these things. I believe the phosphor was
- incorporated into an aerogel, with the tritium applied as a gas
- soaking the block. Sounded neat to me. As I recall, the big
- advantage is much higher light output than traditional tritium-based
- light sources. I remember about 20 years ago Edmund Scientific used
- to sell light sources which were capsules of tritium gas internally
- coated with a phosphor. I wish I had bought one now, but of course it would
- have decayed considerably by now (the half-life of tritium is about 5 years).
