[sdpd] Crystallinity of Nanomaterials

[Narayanan Lakshminarasimhan <nlnsimha...@yahoo.com>]

Dear All,
   
  I would like to know the procedure to estimate the "crystallinity" from powder XRD data for nanomaterials with different crystallite size.  I found in literature about Debye Function Analysis (DFA) for generating the powder pattern for nanoparticles with different size containing different number of atoms in the cluster.  Is there a way to estimate from routine powder XRD data?  
   
  Thanking you in advance,
  Lakshminarasimhan.
