Speedball makes a few glow in the dark screen printing inks, but honestly they kinda double as fabric paint; the ink doesn't know or really care if you put it on using a silk screen or paintbrush.

Speaking of speedball inks, since they're water based, I took a bit of that ink and tried watering it down to see if it could be made into a sort of hobo dye, and am testing it on a piece of scrap fabric. I'll have to iron the test piece (this particular ink is heatset by ironing it) and throw it in the laundry to find out if my idea won't just come off in the wash, but if it actually turns out to be permanent then this becomes just a matter of coloring a pair of white gloves with it, which should be pretty straightforward.

Also I was recently made aware of these two glow in the dark tie dyes, this and this, which if my idea doesn't work, seem like good backups.
