A few people are confused about the conversion of.......1/D nm-1 into 1/r. You need to divide the 1/D values by 2. The formula for the conversion is 1/r = 1/D × (L / λ) / 2. Where: 1/D is the reciprocal space measurement in the SAED pattern. L is the camera length of the TEM. λ is the wavelength of the electron beam. The reason for dividing by 2 is that the diffraction spots in a SAED pattern correspond to the scattering vector, which is defined as: q = 2π / d. Where d is the real-space interplanar spacing. Thank you in advance
Thank you for making this very informative video. I would like to thank you from the bottom of my heart. and one request is to please, kindly make one video on monocrystalline TEM SAED pattern analysis and spacing.
1/r = 2(1/2r) Therefore, when calculating (1/r), you should have multiplied (1/2r) x 2, but I noticed that you are dividing by 2. Can you explain that please?
Excellent video, covered every aspect. I have one question kindly respond to clarify concept of the community. Right from the start, obtaining 1/2r, till matching d spacing you video is very coherent. However, to obtain 1/r (2nd column of the table) from 1/2r, instead of dividing it by 2 (which you did), should we not do the multiplication? i.e. 1/2r * 2 = 1/r
Can I know why the biggest radius on the small circle or inside circle. Instead of outer circle? Suppose (200) should be place at outer circle. I am new to this can you clarify.
You are right, But his is not the mistake. The actual mistake is, I measured 2R but mistakenly labeled it as 1/2R in the first place and then use R instead of I/R. However, the method and calculation is accurate. But you need just to consider the 1/2R as 2R, 1/R as R.
While indexing Miller indices in Microsoft paint, you have indexed the plane corresponding to the least r-value to the outermost circle. I am confused at this point.
Thank you for the tutorial, the math for converting 1/2r into 1/r may not be right. I think you are supposed to multiply not divide by 2. i.e 1/2r is a smaller value than 1/r. please check, thank you for the information
Sir.. please help me to analyse .. I calculated the d spacing but due to lack of jcpds card, I couldn't do it.. will you please provide your email address?
Thank you very much Sir. Please do make more videos on Characterization to help people like us. You are a very good teacher.
Really Very helpful videos.........
Clearly explained all things that we have to do

Very Informative video. Sir please put this type of analysis for all characterization methods
Why you divide 1/2r values to find 1/r values ?
It should be multiplied by 2 not divide
Can I know why the biggest radius on the small circle or inside circle. Instead of outer circle? Suppose (200) should be place at outer circle. I am new to this can you clarify.
I do not have any access to the JCPDS card for my use !! Is there any public domain from where I can access the JCPDS file ?
Thank you very much for the tutorial. Please make a video about the SAED pattern of LRTEM. There is no scale in the SAED pattern
Many thanks. Please make a video on the Single crystal SAED pattern .
Thank you very much for the video sir
Very helpful session
Thankyou sir your vdieo help me alot❤

Thank for your tutorial, it was very helpfull!
You are welcome!
Hello sir, will you plzz make a vedio on the wemple -Didomenico for determining the non- linear refractive index
Going from 1/2r to 1/r, you should have multiplied 2 not divided 2. I do not know how you got the right answer?
Nicely explained work . Thanks 🎉🎉
Thanks and welcome
Thank you for the informative video.
Why didn't you use the formula L•lambda=R•d to find d - spacing?
Is this that you are mentioning the bragg equation?
Nano world plz make such more videos
Thank very much for your usefull video
How to get the jcpds card can you provide the link of your video in comment box?
If the d spacing lower than 1A
How to identify the hkl?
Could you please also make a video on how to index spot diffraction pattern? Really appreciate it.
hello there, do you know how to index spot diffraction pattern?
Kindly provide the JCPDS No for MXene..wonderful video
You are doing really nice work.
Thank you! Cheers!
Very useful videos, go ahead.
Many many thanks
Excellent! Thank you
You are welcome!
Sir, 1/r = 2 times of 1/2r . Then How you did the half of 1/2r for 1/r ???
from C column to D column , it should be 1/2r *2 = 1/r
You are right,
But his is not the mistake. The actual mistake is, I measured 2R but mistakenly labeled it as 1/2R in the first place and then use R instead of I/R.
However, the method and calculation is accurate. But you need just to consider the 1/2R as 2R, 1/R as R.
@@nanoworld6122 yes.. i was wondering the same thing
Thank a lot sir
Thank you so much your video is wonderful.
How can we interpret the HRTEM images of nanoparticles and quantum dots..? Can u explain it in hindi..?
Thank you. awesome!
Glad you liked it!

I think you are right, if 1/2r=n; then 1/r=2n.
But then why it seems to be right when compared with the standard values in the card?
Great explanation, Can I have JCPDS file for Bi2O3
Why did you divide 1/2r to find 1/r?????
Please do a vdo on ac conductivity fitting and how to calculate the atomic positions of a sample for rietveld refinement. Pls. suggest the site.

Thank you.
Very brilliant video. But I am wondering if I am wrong about the 1/2r and 1/r in relative values, if anyone can tell.
I am also think that, 1/2r=a => r= 1/2a, but in this case r is calculated reversely
1/2r is not a 1÷ (2r) its 2r in reciprocal plane
Sir pls upload more tutorials. Pls upload Vesta software tutorial.
