Raman Spectroscopy Crystallite Size Calculator (Tuinstra Koenig Relation)

Laser Wavelength (nm)

ID/IG Ratio

Results
nm

Calculation Tutorial:

STEP1: Open the Raman spectra of the material, which is obtained from the instrument and calculator ID by IG ratio.

STEP2: 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)]^4 / ID:IG Ratio
