Morphology

fluorescent = fluoresce (opaque) = fluoresce + nt

The noun sense is based on the adjective, which is itself derived from a rare verb, so the formation is opaque.

Etymology

Fluorescent used for a light comes from the idea of the glowing mineral fluorite, whose name comes from a Latin root meaning 'to flow', also seen in fluid. So a fluorescent is a lamp that gives a bright, glowing light for rooms.
