Re:Re: [sdpd] ABOUT FWHM PARAMETERS /SHAPE PARAMETER
Hi，
Today, one sample have produced, the sample has a interesting phenomenon which I can not understand.
The sample contains Li Eu W O(Li:Eu:W=1:1:2). Maybe LiEu(WO4)2
question:
1. why about 4 peaks are extremely high, and how can I explain weak peaks? But I cannot match any PDF card. How can I do?
texture? Maybe this sample has small volume? I do not know what it is. And I can not index it.
This sample can emit red light(at 612nm, maybe because of EU3+).
XRD: fast scan in 15 minutes.10-65 degree.
SEM(EDS):EU:W=1:2 and Eu:W=1:1 ,maybe it contains impurity phase.
please advice....thanks in advance!

A quick search in the Fullprof manuals and tutorials should give the
answer to most questions : http://www.ill.eu/sites/fullprof/
