is xrd result supposed to be exactly consistent with SAED? for example in xrd there are 3 peaks detected, in SAED there should be three rings correspondingly as well?
@@smrutismita4229 Selected ares Electron diffraction. We use this technique to know the crystal structure of a sample. Wether it is single or polycrystlline
Hello Sir. SAED pattern only shows diffraction of major phase in polycrystalline material? Also, please tell me if tem micrograph shows both amorphous and crystalline phases then which SAED pattern we should consider for indexing, spots/dots arranged in parallel lines or spots/dots arranged in concentric circles.
Is the way to determine hkl of a single crystal from SAED the same as the explanation in this video? Since we observe bright spots instead of bright rings from a single crystal. Thank you in advance
I think in that case one bright spot represent in single crystalline like a circle in case of polycrystalline. The more bright spots means high intensity while the dim one show less intensity
Thanks a lot, sir. This video is so beneficial. I highly appreciate you for that.
You are always welcome
Hi, I want to know why have you ignored the l. lambda factor in d spacing calculation from r?
Oh I see. If I did ignore it, sorry about that . Lambda is basically the X- rays wavelength
can you please provide the reference of the literature, which mentions that the plane (110) corresponds tp the d-spacing value of 0.50..?
There are many reports available online for all materials. Each material has different d spacing and lattice plan.

True Sir.
@@qamarwali sir can u please say what is SAED?
@@smrutismita4229 Selected ares Electron diffraction. We use this technique to know the crystal structure of a sample. Wether it is single or polycrystlline
@@qamarwali is it a software?
@@smrutismita4229It is not a software. It is a machine just like XRD or SEM.

SAED gives information about the materials as single crystalline or poly. If dot, single whereas concentric circles shows polycrystlline
@@qamarwali Thank you Sir.
Hi sir
How are you?
Sir i have no scale bar given on my SAED data please help me how to interpret my results?
Without scale it is too difficult. How we will know the resolution?
Thank u very much, your videos are very useful
You are welcome

thanks for the explanation sir is it same applicable for single crystal pattern and for that how to determine d spacing..?
Yes for single crystal it would be dots not ring. For d spacing I have made video please check it
Sir..i hv just started m research..so can u please help me that how i interpreate my xrd data
I made other videos in my channel on the same topic exactly. Please watch
