how can i interpert XRD peaks after doping LDH. pure sample matched with JCPDF file as in papers, but after doping newly peaks appear and peaks disappear?
You identified the diffraction pattern with the help of ICCD card. If you need standard data, could you provide the card number? I will send the standard data.
Of course, after LDH doping, a new peaks appear and others disappear;
...But when you find some peaks such as (00l), (0kl) or ( (hkl) , this indicates that you still have an LDH-type lamellar phase - it's not necessary to find all the peaks.
