Fe fluorescence from one of the phases?

Check Fe content via XRF...

Thank you again

The ascending slope in your diffractogram may indicate the presence of amorphous materials or poorly crystalline phases in the soil treated with lime and natural pozzolana.

Abdelhak Maghchiche thank you

Dear Muhammad Farooq Saleem

you should share some details about your sample...

Is it a nano particle one containing some Fe?

One of the slits too large?

How do your XRD pattern look like for well known samples?

By the way, you should file a new question about this issue and not hiding it in the series of answers of old ones...

Best regards

thanks for feedback...

NPs involved?

Any measures to avoid fluorescence background?

Did you switch the x-ray tube ON and OFF during the scan (at about 20 and 95° in 2theta)?

With respect to the peak profiles: you should go for smaller step sizes in theta/2theta ...

Your peaks have net peak heights of about 100 to about 300 cts. Noise of net peaks is sqrt of net peak heights, so about 10 to 17cts. Your background is higher than 1000cts. The background noise is larger than sqrt(1000)~30cts; i.e. at least 10 to 30% of peak heights! So your peaks will suffer from the noise of the background. Thus you should also increase the (local) scan (acquisition) time...

But, I think, the main thing is to get rid of the background.

Make use of a) Co or Cr tube, or b) use monochromatized detector input, or c) energy resolved detection (EDS)...

Balanced filter (Ross filter) approach will remove the fluorescence background, but in your case will still not work here, because the background noise will not be removed but will be increased further...

Good luck and

best regards

Dear Muhammad Farooq Saleem

you have no other choice to take the peaks as they are now. Due to the lack of peak maxima you should here take the center of the peaks as the peak's position; but I think, the your data evaluation will do this automatically...

When presenting the XRD the pattern you should skip the 'increase' and the 'decrease' of the background by restricting the diagram from 25° (or 30°) to 90° in 2theta. Otherwise you will end up in a never ending discussion about this issue with the reviewers.

Muhammad, Jade does read txt files with data as x,y pairs. Right click on the file and select Import..., then select appropriate options on the dialog.

My first thought is that no, that is not publishable. But if you can identify all the peaks (based on their centers, as Gerhard as mentioned) and your proposed phases do not expect any additional peaks, that demonstrates probably correct identification of the phase(s) present - if you succeed in that identification of all peaks and do not expect any missing peaks, it could be good enough to publish, even though it is ugly. (And do trim of the abrupt rise and fall at the left and right edges, respectively.)
