Why were two different phenomena blue shift in UV_Vis spectra and red shift in PL spectra of ZnS nanoparticles obseved?

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...

How can we choose the suitable excitation wavelength to be used in PL measurement of a semiconductor material?

Metal doped ZnS nanoparticles are prepared by chemical route. In PL ( Photoluminescence ) measurement excitation wavelength of 300nm and 325nm are used. In PL spectra same peaks but of different...

Why were different types of ZnS nanostructures formed while it was synthesized by the same method?

e.g in our works we synthesized ZnS colloidal nanoparticles by chemical wet methods taking zinc sulphate and thiorea as starting materials and PVA(polyvinyl alcohol) as capping agent. To our great...
