Etymologically, the entry records: Coined by British physicist George Stokes in 1852 from fluorspar + -escence. Morphologically fluoresce + -ence. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is fluorescence, spelled F-L-U-O-R-E-S-C-E-N-C-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
