The paper (which is very short) said 500-700nm and referenced an older (1997) paper that reported on a bunch of UV and visual emitting living systems. I looked there but didn’t pinpoint an answer. It did mention that the emission doesn’t usually have sharp peaks (as the reason they trade spectral resolution for sensitivity). It seems like the emitting molecules are large, so it’s probably pretty broad.
Its not clear to me either, but since they said visible, my guesses would be 680 nanometers or 490 nanometers, because, well, hydrogen.

Anyway… that made me nice and sleepy.
