Producing or tending to produce fluorescence; capable of generating fluorescent light.
From 'fluorescence' combined with the suffix '-genous' (meaning 'producing' or 'arising from'), creating a near-synonym to 'fluorescigenic' with slightly different etymology.
This is an ultra-technical term that you'd find in advanced chemistry papers rather than everyday speech—it describes substances that intrinsically generate fluorescent light without needing special treatment.
