How to find peak position and FWHM of XRD data - 08

FWHM is used in the Scherrer equation for finding the grain (crystallites) size. Here in this video, I have shown the method for finding FWHM from XRD data using OrigionLab software. If you have any questions regarding this video, please feel free to ask in the comment section below. For more videos, please subscribe to NanoWorld. Thank You.

[@deepaknegi6126]

very beautifully explained/shown .. thank you Sir

[@amdadulhoqibnbahar5602]

what a great video about XRD . you deserve more thx you. please more videos for nano( SEM/TEM

[@nonod3628]

Thank you, very helpful videos

[@thee_ms_enthusiast6030]

Great video. Thank you for this

[@vv-ky4bi]

excellent video man...i am referring your video. keep helping a person like me

[@ppamonha]

Thank you!

[@ZainAli-bq6gd]

the video was very useful... and yes... love that background music.... have you composed it by yourself

[@gyanendrapratapsinghkedars3946]

So helpful, Thank you very much

[@nanoworld6122]

My pleasure....

[@ANP-]

Thank you. God bless you

[@Noor-xh7ix]

if our COD value does not reach near 1 after smoothing what should we have to do?? and how to fit the peak when Fit did not converge. A maximum iteration setting of 400 was reached. any leed will be appreciated.

[@Aksh7414]

Thank you sir for your nice presentation .... I am having trouble in converging the data....nonlinear fit giving only one fwhm value for a whole... And i can fixpeaks... But i cant able to give nlfit.... While integrating the peak i am getiing all things is that correct ?

[@sagarrawal8332]

How to find the corresponding value of y axix acrroding to peak position i.e xc value? Thanks in advance.

[@thuydungnguyen1460]

thanks you so much

[@sakshisatishs]

Hi, I know it's been a while since you have posted this video. I used search and match software for this and I am wondering whether I am able to automatically use the FWHM values they have provided through that software?

[@nanoworld6122]

Yes, you can use it.

[@Muradsahar]

Do we have to click at the max point of each peak? or (y-Values)

[@martinfibela3798]

excellent video and very good way to show something so complex, I like and subscribed. I have a question, the files you use have you shared them?

[@nanoworld6122]

Thank You. Sure, please send me an email at [e-mail] and ask whatever you want.

[@suryatejacv3042]

kindly make a video on the calculation of strain energy from the xrd data

[@miriamsaraicruzleal1521]

Hello, thanks for the video. I have a question. This method applies when we have a mix of materials?

[@nanoworld6122]

Yes

[@07FGF]

Thank you.

[@nanoworld6122]

No worries!

[@md.joherulalamchanchal63]

Hi, thanks for the video. I am having a problem. I am having a error mesage saying " Fit did not converge. Maximum iteration setting of 400 was reached.". WHat should i do to fix this?

[@ambikasaxena4550]

Did you find an answer

sir the data which you use is ZnO materials, please confirm

[@Tounsenk]

Ok, i learned how to deconvolute multi peaks. But now i need to determine the amorphous halo, to calculate Xc (% crystallinity = Area crystallines peaks (Ac) / Ac + Aa (amorphous halo area)). How i can do it?

[@nanoworld6122]

Please watch the complete video, entire process is available in it.

[@priyankarajwani7805]

I have a doubt that after selecting the peaks why does it shows , the peaks did not converge and how to correct this and also I am getting same FWHM values for most of the peaks. Is this ok or not ?

[@soumiabenhouhou4185]

hello, i have a question. what is the difference between the size cristallite obtained with FHWM and the size of particles measured with image j in SEM? please help meeeee for example: i have a size cristallite= 50 nm and the size in SEM=106 nm. hence, it should be the same or there is a difference

[@nanoworld6122]

Thank you for your comment, We calculate particle size from SEM images while crystallites size from XRD data. These two are different things and not necessarily means to be equal. A particle may be made up from single crystallite or from several crystallites. Therefore, the crystallites size will always equal to or less than the particle size.

[@keerthanapadma8742]

TGA and SEM analysis are not accessible. Kindly do check it. Thanks for posting.

[@nanoworld6122]

will be fixed soon. Thanks for reporting.

[@mugdhasahu1871]

(5) Fit did not converge - mutual dependency exists between parameters. You may have overparameterized the fitting function. Fixing one of them may eliminate this problem. what should I do??

[@antoniolopes5748]

HI, I had the same problem...You must subtract the baseline and then apply smooth process. :D

[@vv-ky4bi]

Sir i could not able to get cod value near to 1. I smoothened so many times...wat to do??

[@nanoworld6122]

Select high intensity peaks only. Do not select low intensity peaks. Or Try to do the process for all the peaks by selecting one peak at a time.

[@attahfakeye9184]

It's a nice video. Pls I have XRD data which I am yet to analyze peak position and FWHM and of course mineral identification due to lack of software, can I send my XRD data to you to help me generate them? Thannks

[@nanoworld6122]

yes sure.

Hello sir, I have origin 8 pro , when I go to analysis,and then choose peaks and base lines --- fit multiple peak then it does not open the NL fit then what should I do in that case,please reply sir

[@nanoworld6122]

I'm using the 9.5 version in my tutorials. Therefore, I have no idea about the 8.0 version. Sorry...

[@kvvlniita6024]

i am using 8.0 madam. it must be working. i have done it with 8.5 pro. there is a way you can download origin 8.5 version with crack. The procedure is available on youtube. you can give a try searching how to install origin.

[@rabbiahasanAwan]

Assalam o Alaikum can i send you my XRD data for interpretation?

[@surendrak5841]

Hi, Sir, I am a new learner on Origin, Can you please sent me the Origin 2021 version. It will help my research, Thank you

[@tomo-dm8cp]

Sorry sir. My "fit until converged" always didn't because maximum iteration setting was reached. What have i do?

[@nanoworld6122]

don't select low intensity peaks and correct your baseline

[@gabrielamendoza8016]

HELLO, I GOT MY XRD DATA AND FOLLOWED THE PROCESS BUT MY R^2 IS 1.4432899320127E-15 WHY IT HAPPENS?
