I have synthesized ternary compound silver bismuth sulphide (AgBiS). I have XRD data (2theta and intensity) for the compound. How can I lable peaks in 2theta Vs Intensity graph when I dont have JCPDS card for my material? Can I lable peaks seperately for Ag and Bi2S3 ? Also will it be accepted ?
Dear Sachin Padwal ,
see for example Fig. 2a of:
Article Homogenously hexagonal prismatic AgBiS2 nanocrystals: Contro...
as well as Fig. 2(d) in:
Article AgBiS2 Semiconductor-Sensitized Solar Cells
However these articles deal with AgBiS2 .
You can only label the peaks separately as Ag and Bi2S3 peaks when you have Ag as separate phase and Bi2S3 as separate phase in your sample.
In the case of Ag, having FCC lattice, you can easily calculate the peak positions by yourself and compare them with your pattern...
Best regards
G.M.
Dear Sachin Padwal
Please study others related work.
Or you can use highscore expert software, through which you can match your xrd data with database.
If you you dont have a confident whether AgBiS is not formed and some Ag is segregated first do SEM and EDAX and confirm the single purity. After that if you do not have do the JCPDS data for it, try to solve it by TREOR programe and solve the structure.
One more thing it is not labelling the peak instead indexing the peaks.
@Dharmadoss Sornadurai Sir I have done SEM and EDX analysis and it has confirmed deposition of following elements -Ti,O, Ag,Bi and S. No other impurities are present. Please tell me how to index peak when there is no jcpds card for AgBiS. Can I index for Ag and BiS seperately?
If the impurities are below 5 % then you can try to index and if it is above 5 % then it is an impure phase hence it is difficult to index it.
To get a sustainable solution to your problem, please refer to the preprint article given at link DOI: 10.13140/RG.2.2.27720.65287/3 or at link https://www.researchgate.net/publication/352830671.
How can you independently index the pattern after formed a compound / alloy. First carry out the composition analysis. Then I will try to help you.
