This discussion could use some examples, and there seem to be some named dyes here that are excited by visible light. On the other hand, the simple fact that it was an issue in the replacement of tennis-court artificial lighting shows that UV excitation is a factor in the fluorescence of the dye used for tennis balls. https://www.thermofisher.com/us/en/home/life-science/cell-analysis/cell-analysis-learning-center/molecular-probes-school-of-fluorescence/fluorescence-basics/fluorescence-fundamentals/light-spectrum-fluorescence.html#excitation https://www.thermofisher.com/us/en/home/life-science/cell-an...
