Dear Ghasem Rahimi,
If you are not sure which solvent to use, start with non-deuterated solvents until you find the appropriate solvent. The most used NMR solvent by organic chemists is deuterated chloroform (CDCl3).

There are a myraid set of attributes to solvent selection for liquid state NMR, key to it being solubility. Would advise consulting an organic chemistry handbook. If your materials are solid carbon-based (e.g. graphitic carbon), NMR may be difficult due to the Carbon-13 isotope being quite readily detected. Would advise Raman spectroscopy, absent of solvent.
As suggested earlier, there is a wide range of NMR solvents depending on the solubility of the material. Usually, DMSO-d6 dissolves most organic compounds and some inorganic materials for liquid state NMR analysis. You may however wish to explore the possibility of solid state NMR if its a material that is not soluble in any NMR solvent. solid state NMR is very useful in cellulose characterisation and I reckon it should be suited for carbon based materials as well. I hope this helps. Do check the article in the link below
