It seems that "IR" LEDs are in the 850-950nm range.  If I remember right,
there are some favorite points, possibly because of particular compounds
used.  I sortof recall 870nm and 940nm as popping up often.  In practise,
most receivers will work with a emitter anywhere in that range, especially
at close range.  Take a look at the -3dB wavelength range of a common
receiver.
