XRD peak of carbon dots at 19 degrees...please help me in knowing what (hkl values) does the peak correspond to
Dear Manasa
Generally, using the Bragg's Law of diffraction, you can calculate d-spacing parameter. By using the lattice parameter (a) and d-spacing (d), you can easily calculate the Miller indices of the plane which is correlated to the XRD peak. For cubic symmetry: d = a/sqrt(h^2+k^2+l^2).
In addition, you can use the following questions, where the same issues were discussed.

Best regards
It seems to be 002 graphite peak with increased interlayer spacing due to the high degree of functionalization (similar to graphene oxide). I recommend to find several papers with XRD of CDs, you will find a lot of XRD patterns with 002 peak at different 2theta.
Hi
Please check the peaks with JCDPCS file. It will give u correct results
