Morphology
The meaning 'a dye that emits visible light when excited' is directly and transparently derived from combining the adjective 'fluorescent' (producing a visible glow when excited) with the noun 'dye' (a coloring material). This simple adjective+noun composition follows common semantic composition patterns and would be understandable to a B1 learner who knows both constituent words, despite the slightly technical register.
Etymology
Fluorescent dye combines two words that give a clear picture: dye is a colour added to something, and fluorescent means it 'glows' under certain light. Imagine painting a small spot that suddenly lights up so you can see and 'track' it, and that's why the term means a dye used to make things easy to see under light.
