There are lots of dyes that can be used for pan films. I can make t-grain emulsion, and theoretically, sensitize for panchromatic films. However, I am working in safelight using my own arms, so I can't handle pan emulsions. If you pay to build a facility for me, I can make it for you :-)
The best I've tried so far is infrared emulsion (in green safelight). But this is still painful to make practically usable plates in very dim light (or the emulsion will fog).
