Raman Spectroscopy Crystallite Size Calculator (Tuinstra Koenig Relation)
ID/IG Ratio (D/G Peak)
STEP1: Open the Raman spectra of the material, which is obtained from the instrument and calculator ID by IG ratio.
STEP3: Now enter the Wavelength of Laser used during the Raman Characterization; also measured ID/IG Ratio (for example 0.9733) in “ID/IG Ratio (D/G Peak)” column of the calculator. You should get the calculated results of the d value in the “Results” field.
Theory Behind Calculations:
The above calculator is based on the “Tuinstra Koenig Relation” to calculate the crystallite size by using Raman Spectroscopy.
Tuinstra Koenig Relation:
Crystallite Size (La) = 2.4×10^-10 × Wavelength of Laser (nm) / ID:IG Ratio
