Dear Konika Choudhury ,

your SEAD pattern has got no spots and no sharp rings.

That is a clear sign, that you have got amorphous material; at least for that spot of your sample

For a comparison of SEAD pattern of amorphous and crystalline material please see for example Fig. 5 of at page 11 of full-text document (= page 175 of publication):

Article First Glass Electrode and its Creators F. Haber and Z. Kleme...

See also for example:

and compare with your case...

For an introduction into electron diffraction you may have for example a look at:
