Magnetic Control of the Manganese Photoluminescence in Fe₃O₄/l-Cys ZnS:Mn Nanocomposites.

ABSTRACT: We investigated the magnetic control of the Mn photoluminescence (PL) in iron oxide/l-cysteine-capped zinc sulfide (Fe₃O₄/l-cys ZnS:Mn) nanocomposites via temperature- and field-dependent PL intensity studies. Fe₃O₄/l-cys ZnS:Mn was synthesized following a wet chemical deposition route and then its physicochemical, morphological, and magnetic properties were characterized. X-ray diffraction analysis indicates the formation of a semiconducting composite material with coexisting phases with high crystalline quality and purity. Electron microscopy reveals that the surfaces of the nanoparticles are clean and smooth, sized between 15 and 30 nm, without any sheathed amorphous phase. Vibrating sample magnetometry and UV light excitation show a clear sup
