Nanotube diameter versus emitting wavelength

[Bruce Haawkins]

Can somebody please help me I am looking for the diameter required of a carbon nanotube to emit a wavelength of 800 nm. If I could just find a graph of nanotube diameter versus emitting wavelength.

There seem to be several modes for nanotube radiation. I found a useful reference as follows:-

One of the modes of nano tube radiation seems to depend on length, just as for a metal rod, but there are others to study.

Thanks do you have a chapter on what range of wavelengths such a set of modes will absorb?
