I haven't looked to see if there are values for graphite / graphene, but http://refractiveindex.info/ has n and k data for many different materials, so you might find the data there.

Thanks for the information Ross. The database suggested has no information about graphene / graphite at high temperatures.

This paper has a dispersion table on p389 for pyrolytic graphite, 400-700nm and T range of 25-600°C:

Thanks a lot Ross for the paper. I need data for IR Range also, if possible.
