Can we predict/explain fluorescence behavior (conventional steady-state fluorescence spectra) of a material like quantum dot, perovskite, etc. from its pXRD data? Whether the lattice plane arrangement have a major role in fluorescence behavior of these type of materials?
Dear Saptarshi Mandal ,
X-ray diffraction (XRD) and x-ray fluoresecence (XRF) are two different physical phenomena.
'Lattice plane arrangement', as you call it, is responsible for the peak positions and the distribution of the chemical elements in these planes and is (among other parameters) responsible for the peak heights (better peak integrals).
X-ray fluorescence is a physical property of the atoms themselves, their electron shells, especially the inner ones.
A change of lattice spacing or even the arrangement in the lattice does not affect the energy levels of the electrons bound at the inner shells.
So fluoresecence will not change with respect to the position(s) of the energy positions of fluoresecence lines.
However, if a change of chemical position is associated with a change in your 'lattice plane arrangement',a change of XRF peak height distribution will be the consequence due to
a) this change of at% numbers in the sample and
b) due to a change of internal x-ray attenuation in the sample by this change of chemical composition.
Good luck for your research and
best regards
G.M.
