Reference for broader spectral lines? I'm looking for some reference listing spectral lines outside the visible spectrum.  (In particular, I'm looking for an element or compound that emits strongly in the 700-900nm range.)
Assuming your question is a reference request:

I now about one resource that has a very broad range of spectral data, the

NIST Atomic Spectra Database Lines Form

This has worked great for me.

This page lists a couple of different alternatives. For the near IR case you are interested in, several collections are listed here.
