During the microwave synthesis of HAp using EDTA as a complexing agent, we found 2-D nanostructures.
Usually when you use a ligand that promotes growth in a particular dimension we're looking at anisotropic growth. Did you try playing with EDTA concentration?
Dear Vijay,
Most of the 1D and 2D crystal growth are associated with epitaxially aligned Oriented Attachment growth mechanism. Below are 2 articles that I found to be very useful during my research on nanocrystal growth. These may not be directly related to the material that you are trying to synthesize, but the detail growth mechanism explanation will help you to deduce a hypothesis for your work. Hope this helps.

Coarsening of Nanocrystalline ZnS
