Luminescence characteristics and surface chemical changes of nanocrystalline Mn doped ZnAl2O4 powder phosphors are presented. X-ray photoelectron spectroscopy (XPS) was used to determine the chemical composition of the possible compounds formed on the surface as a result of the prolonged electron beam exposure. A stable Al2O3 layer was formed on the surface and is possibly contributing to the CL stability of the ZnAl2O4:Mn phosphor.
