Chlorophyll and billirubin fluoresce with blue light with a frequency of about 460nm.
There is an interesting link here showing the structure of heme (blood from which billirubin is derived) and chlorophyll (image from the link):
You can see how an unwound (my term) heme create the billirubin structure:
The fluorescence is described here and can be triggered with common plant lights:
