Malvern Zetasizer Nano ZS ZEN3600 Dynamic Light Scattering ...

Applica2on note: InvesLgaLon into the locaLon of dopant ions in semiconductor nanoparLcles Ø Zetasizer Nano ZS was used to invesLgate the zeta potenLal of ZnO nanoparLcles doped with Mn and Co. Ø The zeta potenLal of 5 at% Co-­‐doped ZnO was nearly idenLcal with the value of undoped ZnO, indicaLng that Co did not precipitated out on the parLcle surface as a separate phase. Ø On the other hand, the zeta potenLal of 5 at% Mn-­‐doped ZnO was lower than that of undoped ZnO, affected by the negaLve charge from Mn oxides that are precipitated on the parLcle surface.
