crystallinity is related to the degree of order and the crystal size of a given crystalline substance.
Crystallinity index (CI) is a quantitative indicator of crystallinity.
The degree of crystallinity has a big influence on hardness, density, transparency and diffusion.
Various techniques, such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy, and many methods based on these techniques could be used to define the CI of a substance.
Scanning electron microscopy (SEM) could be utilized as a supplementary technique to observe the morphological changes during a process which involves the crystalline substance.

'How can I calculate the crystallinity index using XRD, SEM and TEM results?'
'What are the crystallinity index significance and its indications?'
If you don't know what the crystallinity index is and its significance, then you have no need to calculate it. You're putting the horse before the cart...
Similarly searching on this forum before posting your question will provide the answer. Google "Rietveld"... See attached.
