I'm looking for a "short wave pass" material that absorbs above 1 microm

Hi

I've been looking for a material that absorbs radiation 1-1.1 $$\mu$$m but does not absorb radiation around 910 $$\pm$$10 nm.

I've looked at several dyes but they all seam to have very long tails causing some absorption at the lower wavelengths.

What I would really like is a graph that displays the absorption spectra for several materials around 1 $$\mu$$m. http://www.photochemcad.com/" [Broken] sort if does this, but, it seam to focus more on the visible spectrum.

Thanks for reading, I'm grateful for any response!
