I have raman spectra of Graphene oxide nanoparticles. The laser wavelength is 1064 nm. I can't find any literature with this wavelength. I had no choice with the laser wavelength that's why I took using 1064 nm. I'm new to this. Kindly help me with this. I have attached the raman spectra.
You can analyse the Raman spectra of GO using the following links:

D/G bands of GO:
The distorted/dissimilar structure of GO generates D-band, which is occurred from the resonance Raman spectra of disorder sp2 hybridized carbon systems containing materials.
The G-band arises from the stretching of the C-C bond in GO, and is common to all sp2 carbon systems due to the E2g mode, occurred at about 1583 cm-1, and at the Γ-point.

In Raman spectra, the laser wavelengths varies from ultra-violet through visible to near infra-red . Typical examples (but are not limited to):
- Ultra-violet: 244 nm, 257 nm, 325 nm, 364 nm
- Visible: 457 nm, 473 nm, 488 nm, 514 nm, 532 nm, 633 nm, 660 nm
- Near infra-red: 785 nm, 830 nm, 980 nm, 1064 nm

Thank you all for replying. Please let me know the approximate value for ID/IG ratio. Shall I use integrated peak area for calculating the same
