In UV-Visible measurement , blue shift was observed at absorption edge of ZnS nanoparticle prepared by CBD (chemical bath deposition ). On the other red shift was found in the PL spectra of the same specimen. Why do we have this two different phenomena in the same specimen when they were characterized by UV-visible and PL spectroscopy ?

I think this can be assigned to the Stokes shift through which the difference between the band maxima in the absorption peak of UV-vis relative to the emission peak measurement in the PL test will be described.

What is the blue/red shift compared to? How were the spectra measured?
